The French adaptation of the Health of the Nation Outcome Scale for Children and Adolescents Self-Rated Form (F-HoNOSCA-SR): Validation and clinical routine use.

The current study aimed to explore the validity of an adaptation into French of the self-rated form of the Health of the Nation Outcome Scales for Children and Adolescents (F-HoNOSCA-SR) and to test its usefulness in a clinical routine use. One hundred and twenty nine patients, admitted into two inpatient units, were asked to participate in the study. One hundred and seven patients filled out the F-HoNOSCA-SR (for a subsample (N=17): at two occasions, one week apart) and the strengths and difficulties questionnaire (SDQ). In addition, the clinician rated the clinician-rated form of the HoNOSCA (HoNOSCA-CR, N=82). The reliability (assessed with split-half coefficient, item response theory (IRT) models and intraclass correlations (ICC) between the two occasions) revealed that the F-HoNSOCA-SR provides reliable measures. The concurrent validity assessed by correlating the F-HoNOSCA-SR and the SDQ revealed a good convergent validity of the instrument. The relationship analyses between the F-HoNOSCA-SR and the HoNOSCA-CR revealed weak but significant correlations. The comparison between the F-HoNOSCA-SR and the HoNOSCA-CR with paired sample t-tests revealed a higher score for the self-rated version. The F-HoNSOCA-SR was reported to provide reliable measures. In addition, it allows us to measure complementary information when used together with the HoNOSCA-CR.

CO2-päästötaseenhallinta terästeollisuudessa

Tämän diplomityön tavoitteena oli kehittää hiilidioksiditaseen hallintamenetelmää Rautaruukin toiminnoille päästökaupan olosuhteissa. Taseenhallintamenetelmä sisältää päästöjen laskennan sekä päästöoikeuksien hallintaan liittyviä asioita. EU:n laajuisen päästökaupan reunaehdot määrittelee päästökauppadirektiivi ja sen antama päästöjen seurantaa ja raportointia koskeva monitorointiohje. Työssä on tarkasteltu hiilidioksidipäästöhistoriaa ja laskentamenetelmiä niiden Rautaruukin toimipaikkojen kohdalta, joiden oletetaan kuuluvan EU:n päästökaupan piiriin. Toimipaikoista on tarkasteltu erityisesti Raahen ja Koverharin terästehtaita, sillä ne muodostavat merkittävimmän osuuden konsernin Suomen toimipaikkojen hiilidioksidipäästöistä. Muita tarkasteltavia toimipaikkoja ovat Hämeenlinnan ja Dalsbrukin valssaamot Suomessa, Smedjebackenin terästehdas ja Boxholmin valssaamo Ruotsissa, Mo i Ranan terästehdas ja Profilerin valssaamo Norjassa sekä Nedstaalin valssaamo Hollannissa. Kustannustehokkaan ja hallitun päästökaupankäynnin perustaksi yritystasolla tarvitaan päästötaseenhallintamenetelmä, jonka avulla voidaan määrittää syntyneet päästöt komission monitorointiohjeen vaatimalla tavalla, arvioida tulevia päästömääriä sekä hallita päästökaupankäyntiä. Päästökaupanhallintaan sisältyviä asioita ovat saadut ilmaiset päästöoikeudet, ostettavien tai myytävien oikeuksien määrä, kaupankäynnin ajankohta, päästöoikeuksien erilaiset hankintamahdollisuudet, päästöoikeuksien hinnanmuodostus ja riskienhallinta.

Coffee polyphenols change the expression of STAT5b and ATF-2 modifying cyclin D1 levels in cancer cells

Background: Epidemiological studies suggest that coffee consumption reduces the risk of cancer, but the molecular mechanisms of its chemopreventive effects remain unknown. Objective: To identify differentially expressed genes upon incubation of HT29 colon cancer cells with instant caffeinated coffee (ICC) or caffeic acid (CA) using whole genome microarrays. Results: ICC incubation of HT29 cells caused the overexpression of 57 genes and the underexpression of 161, while CA incubation induced the overexpression of 12 genes and the underexpression of 32. Using Venn-Diagrams, we built a list of five overexpressed genes and twelve underexpressed genes in common between the two experimental conditions. This list was used to generate a biological association network in which STAT5B and ATF-2 appeared as highly interconnected nodes. STAT5B overexpression was confirmed at the mRNA and protein levels. For ATF-2, the changes in mRNA levels were confirmed for both ICC and CA, whereas the decrease in protein levels was only observed in CA-treated cells. The levels of cyclin D1, a target gene for both STAT5B and ATF-2, were dowregulated by CA in colon cancer cells and by ICC and CA in breast cancer cells. Conclusions: Coffee polyphenols are able to affect cyclin D1 expression in cancer cells through the modulation of STAT5B and ATF-2.

Vers une intégration des connaissances: dialogue épistémologique entre science forensique et criminologie

Bien que la science forensique et la criminologie partagent un objet commun, le crime comme réalité physique et sociale, elles tendent à se construire de manière indépendante et ont une propension à se profiler comme des disciplines bien établies et distinctes l'une de l'autre. A contre-courant, le présent article esquisse des pistes de réflexion sur le projet de construction de connaissances avancé par une cohorte de chercheurs convaincus de l'attrait de l'interface entre criminologie et science forensique. En particulier, nous visons à stimuler le débat et amorcer une réflexion croisée sur la manière dont le phénomène criminel est érigé en objet de connaissance, tant en science forensique qu'en criminologie. Nous affirmons que ces deux champs d'étude d'un même objet ont plus en commun que leurs praticiens ne le prétendent et proposons un dialogue visant à entrevoir les bénéfices d'une démarche à la fois plus ouverte et plus entremêlée de la criminologie et de la science forensique

Biological variation of established and novel biomarkers for atherosclerosis: Results from a prospective, parallel-group cohort study.

BACKGROUND: Biomarkers are a promising tool for the management of patients with atherosclerosis, but their variation is largely unknown. We assessed within-subject and between-subject biological variation of biomarkers in peripheral artery disease (PAD) patients and healthy controls, and defined which biomarkers have a favorable variation profile for future studies. METHODS: Prospective, parallel-group cohort study, including 62 patients with stable PAD (79% men, 65±7years) and 18 healthy control subjects (44% men, 57±7years). Blood samples were taken at baseline, and after 3-, 6-, and 12-months. We calculated within-subject (CVI) and between-subject (CVG) coefficients of variation and intra-class correlation coefficient (ICC). RESULTS: Mean levels of D-dimer, hs-CRP, IL-6, IL-8, MMP-9, MMP-3, S100A8/A9, PAI-1, sICAM-1, and sP-selectin levels were higher in PAD patients than in healthy controls (P≤.05 for all). CVI and CVG of the different biomarkers varied considerably in both groups. An ICC≥0.5 (indicating moderate-to-good reliability) was found for hs-CRP, D-Dimer, E-selectin, IL-10, MCP-1, MMP-3, oxLDL, sICAM-1 and sP-selectin in both groups, for sVCAM in healthy controls and for MMP-9, PAI-1 and sCD40L in PAD patients. CONCLUSIONS: Single biomarker measurements are of limited utility due to large within-subject variation, both in PAD patients and healthy subjects. D-dimer, hs-CRP, MMP-9, MMP-3, PAI-1, sP-selectin and sICAM-1 are biomarkers with both higher mean levels in PAD patients and a favorable variation profile making them most suitable for future studies.

Immunodeficiency and the risk of cervical intraepithelial neoplasia 2/3 and cervical cancer: A nested case-control study in the Swiss HIV cohort study.

HIV-infected women are at increased risk of cervical intraepithelial neoplasia (CIN) and invasive cervical cancer (ICC), but it has been difficult to disentangle the influences of heavy exposure to HPV infection, inadequate screening and immunodeficiency. A case-control study including 364 CIN2/3 and 20 ICC cases matched to 1,147 controls was nested in the Swiss HIV Cohort Study (1985-2013). CIN2/3 risk was significantly associated with low CD4+ cell counts, whether measured as nadir [odds ratio (OR) per 100-cell/μL decrease = 1.15, 95% CI: 1.08, 1.22], or at CIN2/3 diagnosis (1.10, 95% CI: 1.04, 1.16). An association was evident even for nadir CD4+ 200-349 versus ≥350 cells/μL (OR = 1.57, 95% CI: 1.09, 2.25). After adjustment for nadir CD4+, a protective effect of >2-year cART use was seen against CIN2/3 (OR versus never cART use = 0.64, 95% CI: 0.42, 0.98). Despite low study power, similar associations were seen for ICC, notably with nadir CD4+ (OR for 50 vs. >350 cells/μL= 11.10, 95% CI: 1.24, 100). HPV16-L1 antibodies were significantly associated with CIN2/3, but HPV16-E6 antibodies were nearly exclusively detected in ICC. In conclusion, worsening immunodeficiency, even at only moderately decreased CD4+ cell counts, is a significant risk factor for CIN2/3 and cervical cancer.

Fast spin echo imaging of carotid artery dynamics.

PURPOSE: We propose the use of a retrospectively gated cine fast spin echo (FSE) sequence for characterization of carotid artery dynamics. The aim of this study was to compare cine FSE measures of carotid dynamics with measures obtained on prospectively gated FSE images. METHODS: The common carotid arteries in 10 volunteers were imaged using two temporally resolved sequences: (i) cine FSE and (ii) prospectively gated FSE. Three raters manually traced a common carotid artery area for all cardiac phases on both sequences. Measured areas and systolic-diastolic area changes were calculated and compared. Inter- and intra-rater reliability were assessed for both sequences. RESULTS: No significant difference between cine FSE and prospectively gated FSE areas were observed (P = 0.36). Both sequences produced repeatable cross-sectional area measurements: inter-rater intraclass correlation coefficient (ICC) = 0.88 on cine FSE images and 0.87 on prospectively gated FSE images. Minimum detectable difference (MDD) in systolic-diastolic area was 4.9 mm(2) with cine FSE and 6.4 mm(2) with prospectively gated FSE. CONCLUSION: This cine FSE method produced repeatable dynamic carotid artery measurements with less artifact and greater temporal efficiency compared with prospectively gated FSE.

The influence of a certain volume of fluid in the lower tear meniscus on intraocular pressure measurements using the non-contact tonometer

Background: Intraocular pressure (IOP) is the pressure inside the eye that helps to maintain the integrity and the suitable form of the ocular globe. Precise and accurate measures of IOP are needed for the diagnosis as well as follow-up of glaucoma. In daily clinical practice, Goldmann applanation tonometer (GAT) and Non-contact tonometer (NCT) are the most common devices for measuring IOP. A close agreement between these methods has been showed, particularly in normotensive patients and a poor agreement, especially when IOP levels are above the normal range. Ophthalmologists have noticed a poor agreement between NCT and GAT, observing that by using NCT and after comparing with GAT, there is an overestimation of IOP readings, and particularly it occurs when the eyes are tearful. Previous studies investigate the effect of tears in Non-contact tonometer readings by the instillation of artificial tears, concluding in one of the studies that the variation was less than 1mmHg and not clinically significant, in contrast with another study which the increases were sadistically significant. Tear menisci are a thin strip of tear fluid located between the bulbar conjunctiva and the eyelid margins. We think that the overestimation of IOP readings using NCT could be due to the presence of a higher volume of tear in the lower tear meniscus which might cause an optical interference in the optoelectronic applanation monitoring system of this deviceObjectives: To research the influence of a certain volume of fluid in the lower tear meniscus on IOP measurements using the NCT in healthy eyes. Moreover, to investigate the agreement between IOP readings obtained by NCT and GAT in the presence and absence of this volume of fluidMethods: The study design will be transversal for diagnostic tests of repeated measures. We will study patients with no ocular pathology and IOP<21mmHg. It will consist in the measurement of IOP using NCT before and after the instillation of COLIRCUSÍ FLUOTEST, used as a volume of fluid in the lower tear meniscus, to observe if there will be differences using the paired t-test. Moreover, we will take IOP measures by GAT in order to know the agreement between these methods after and before the application of these eyedrops, using the ICC (intraclass correlation coefficient) and the Bland-Altmann method

Clinical usefulness of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) scale in patients with type I bipolar disorder

Background: The relevance of persistent cognitive deficits to the pathogenesis and prognosis of bipolar disorders (BD) is understudied, and its translation into clinical practice has been limited by the absence of brief methods assessing cognitive status in Psychiatry. This investigation assessed the psychometric properties of the Spanish version of the Screen for Cognitive Impairment in Psychiatry (SCIP-S) for the detection of cognitive impairment in BD. Methods: After short training, psychiatrists at 40 outpatient clinics administered the SCIP three times over two weeks to a total of 76 consecutive type I BD admissions. Experienced psychologists also administered a comprehensive battery of standard neuropsychological instruments to clinical sample and 45 healthy control subjects. Results: Feasibility was supported by a brief administration time (approximately 15 minutes) and minimal scoring errors. The reliability of the SCIP was confirmed by good equivalence of forms, acceptable stability (ICC range 0.59 to 0.87) and adequate internal consistency (Chronbach's alpha of 0.74). Construct validity was granted by extraction of a single factor (accounting 52% of the variance), acceptable correlations with conventional neuropsychological instruments, and a clear differentiation between bipolar I and normal samples. Efficiency was also provided by the adequate sensitivity and specificity. Limitations: The sample size is not very large. The SCIP and the neurocognitive battery do not cover all potentially relevant cognitive domains. Also, sensitivity to change remains unexplored. Conclusion: With minimal training, physicians obtained a reliable and valid estimate of cognitive impairment in approximately 15 minutes from an application of the SCIP to type I BD patients.

Medida da espessura do segmento uterino inferior em gestantes com cesárea prévia: análise da reprodutibilidade intra- e interobservador por ultra-sonografia bi- e tridimensional

OBJETIVO: comparar a reprodutibilidade intra- e interobservador da medida da espessura total do segmento uterino inferior (SUI), por via abdominal, e da medida da camada muscular, por via vaginal, usando ultra-sonografia bi- e tridimensional. MÉTODOS: foi estudada a medida da espessura do SUI de 30 gestantes com cesárea anterior, entre a 36ª e a 39ª semanas, por dois observadores. Foi efetuada abordagem ultra-sonográfica abdominal com a paciente em posição supina e vaginal em posição de litotomia. No corte sagital, foi identificado SUI e foram coletadas quatro imagens bidimensionais e dois blocos tridimensionais da espessura total por via abdominal e o mesmo da camada muscular por via vaginal. As aquisições tridimensionais foram manipuladas no modo multiplanar. O tempo foi cronometrado. A reprodutibilidade foi avaliada pelo cálculo da diferença absoluta entre todas as medidas, proporção de diferenças menores que 1 mm, coeficiente de correlação intraclasse (ICC) e limites de concordância de Bland e Altman. RESULTADOS: a medida da espessura média do SUI por via abdominal bidimensional foi de 7,4 mm e, por via vaginal, de 2,7 mm; a tridimensional foi 6,9 mm abdominal e 5,1 mm vaginal. Reprodutibilidade intra- e interobservador da via vaginal versus abdominal: menor diferença absoluta (0,2-0,4 versus 0,8-1,5 mm), maior proporção de diferenças (85,8-97,8 versus 48,7-72,8%) com p<0,0001, versus ICC (0,8-0,9 versus 0,6-0,8) e menores limites de concordância (-0,9 a 1,5 versus -3,8 a 4 mm) para via vaginal. Ultra-sonografia tri- versus bidimensional: menor diferença absoluta (0,2-1,4 versus 0,4-1,5 mm), maior proporção de diferenças (57,7-97,8 versus 48,7-91,7%) com p>0,05 e menores limites de concordância (-3,8 a 3,4 versus -3,6 a 4 mm) para ultra-sonografia tridimensional e ICC semelhantes (0,6-0,9 versus 0,7-0,9). CONCLUSÕES: do exposto, concluímos que a medida da espessura da camada muscular do SUI por via vaginal utilizando a ultra-sonogafia tridimensional é mais reprodutível. Nossos resultados, porém, não indicam que essa medida tenha implicação clínica para predição de rotura uterina, que não foi objeto deste estudo. O único trabalho que correlacionou a espessura do SUI com risco de rotura uterina, sem interferir na conduta do obstetra ou antecipar o parto, foi feito por medidas bidimensionais abdominais da espessura total.

Validação de versão para o português de questionário sobre qualidade de vida para mulher com endometriose (Endometriosis Health Profile Questionnaire - EHP-30)

OBJETIVO: desenvolvimento da versão em português brasileiro do Endometriosis Health Profile Questionnaire (EHP-30), adaptação transcultural ao Brasil e avaliação das medidas psicométricas do EHP-30 Português em amostra brasileira. MÉTODOS: o instrumento original em inglês foi vertido para o português, seguindo diretrizes internacionais, passando por todas as etapas de tradução, retrotradução e comparação das versões para adaptação transcultural, validade de face e de conteúdo. O EHP-30 Português foi aplicado a uma amostra de 54 pacientes com diagnóstico de endometriose para análise de consistência interna, usando o alfa de Cronbach. A fidedignidade teste-reteste foi avaliada pelo coeficiente de correlação intraclasse (ICC). Para a avaliação de validade de construto convergente foi testada correlação entre o EHP-30 Português, WHOQOL-Bref e o Inventário de Depressão de Beck (BDI). RESULTADOS: a avaliação da consistência interna apresentou valores de α=0,8 a 0,9, sugerindo homogeneidade entre as questões. A fidedignidade teste-reteste apresentou ICC de 0,8 a 0,9, demonstrando estabilidade do instrumento. Na validação de construto, demonstraram-se fortes correlações da escala de auto-imagem do EHP-30 com os domínios físico (-0,6) e psicológico (-0,6) do WHOQOL-Bref e da escala de suporte social com o BDI (0,5), evidenciando-se, assim, boa correlação com outros instrumentos de avaliação de qualidade de vida. CONCLUSÕES: o EHP-30 Português mostrou ser um instrumento de fácil e rápida aplicação e bem aceito pelas pacientes, apresentando bom desempenho psicométrico, com medidas de fidedignidade adequadas (consistência interna e fidedignidade teste-reteste) e validade de construto. Estes resultados demonstram que o EHP-30 Português é um instrumento adequado para avaliação de qualidade de vida em mulheres brasileiras com endometriose em ambiente clínico e de pesquisa.

Expressão da proteína erbB-2 e dos receptores de hormônios na transição das regiões in situ para invasora de tumores da mama

OBJETIVOS: avaliar a expressão de erbB-2 e dos receptores hormonais para estrógeno e progesterona (RE/RP) nas regiões de transição entre as frações in situ e invasoras de neoplasias ductais da mama (CDIS e CDI, respectivamente). MÉTODOS: oitenta e cinco casos de neoplasias mamárias, contendo regiões contíguas de CDIS e CDI, foram selecionados. Espécimes histológicos das áreas de CDIS e de CDI foram obtidos através da técnica de tissue microarray (TMA). As expressões da erbB-2 e dos RE/RP foram avaliadas por meio de imunoistoquímica convencional. A comparação da expressão da erbB-2 e dos RE/RP nas frações in situ e invasoras da mama foi realizada com emprego do teste de McNemar. Os intervalos de confiança foram determinados em 5% (p=0,05). Foram calculados coeficientes de correlação intraclasse (ICC) para avaliar a concordância na tabulação cruzada da expressão de erbB-2 e RE/RP nas frações de CDIS e CDI. RESULTADOS: a expressão da erbB-2 não diferiu entre as áreas de CDIS e CDI (p=0,38). Comparando caso a caso suas áreas de CDIS e CDI, houve boa concordância na expressão da erbB-2 (coeficiente de correlação intraclasse, ICC=0,64), dos RP (ICC = 0,71) e dos RE (ICC = 0,64). Considerando apenas tumores cujo componente in situ apresentasse áreas de necrose (comedo), o ICC para erbB-2 foi de 0,4, comparado a 0,6 no conjunto completo de casos. Os ICC não diferiram substancialmente daqueles obtidos com o conjunto completo de espécimes em relação aos RE/RP: para RE, ICC=0,7 (versus 0,7 no conjunto completo), e para RP, ICC=0,7 (versus 0,6 no conjunto completo). CONCLUSÕES: nossos achados sugerem que as expressões de erbB-2 e RE/RP não diferem nos componentes contíguos in situ e invasivo em tumores ductais da mama.
