    Plasma steroid concentrations measured in the post-menopausal women with breast cancer showed a close correlation between the various androgens. The post-menopausal women exhibited a correlation between estrogen receptors (ER) and "arterial" 17 alpha-hydroxyprogesterone levels in the breast. ER levels expressed as a function of plasma (arterial) steroid (P/17 P) molar concentration ratio were distributed within a hyperbola, suggesting the existence of a control mechanism for breast cell ER levels

    International audienceObjectives: To validate the Psychogeriatric Inventory of Disconcerting Symptoms and Syndromes (PGI-DSS), a single scale in A4 format comprising four disconcerting syndromes (violence, refusal, words, and acts). The scale enables an immediate conversion of a qualitative assessment to a quantitative assessment. The PGI-DSS was compared with the Neuro Psychiatric Inventory for Nursing Homes (NPI-NH).Design: Cross-sectional descriptive and correlational studies.Setting: Thirty geriatric care units and nursing homes.Participants: Raters interviewed nurses and nursing assistants in charge of older adults hospitalized in geriatric care units or living in nursing homes (N = 226).Measurements: The French version of the PGI-DSS and the French version of the NPI-NH.Results: The correlation coefficient between the PGI-DSS and the NPI-NH was 0.70 (p < 0.0001). The PGI-DSS threshold score corresponding to the NPI threshold score was 17 (specificity: 87%, sensitivity: 63%). Four statistical factors, corresponding to the four clinical syndromes, explained 53.4% of the total variance. The internal consistency of the PGI-DSS (Cronbach's alpha = 0.695) was higher than that of the NPI-NH (Cronbach's alpha = 0.474). Test-retest reliability was better for the PGI-DSS than for the NPI-NH. The intraclass correlations were 0.80 [0.73; 0.86] and 0.75 [0.67; 0.83], respectively. Interrater reliability was better for the PGI-DSS than for the NPI-NH. The intraclass correlations were 0.65 [0.55-0.76] and 0.55 [0.43-0.68], respectively.Conclusion: The PGI-DSS was developed to overcome the limitations of the NPI-NH. New, brief, easy to administer in less than 4 minutes, foldable in four parts, pocket-sized, easy-to-read in the palm of the hand, PGI-DSS could have similar or better statistical properties than the NPI-NH. Whereas the 10 domains in the NPI-NH have clinical utility for clinicians, the four easily understandable syndromes in the PGI-DSS can help avoid inappropriate attitudes and can guide psychosocial interventions. It could likewise improve dialogue between caregivers and clinicians

    De par leur habitat hydrique et leur mode d'alimentation, les coquillages sont susceptibles d'hĂ©berger des bactĂ©ries pathogĂšnes responsables de toxi-infections alimentaires parmi lesquelles les salmonelloses imposent une vigilance toute particuliĂšre.La technique employĂ©e Ă  ce jour ne rĂ©pondant pas aux exigences de rapiditĂ© et simplicitĂ© souhaitĂ©es par les laboratoires, nous avons testĂ© une nouvelle mĂ©thode rapide, associant un prĂ©-enrichissement de courte durĂ©e Ă  l'emploi d'une gĂ©lose spĂ©cifique (milieu de RAMBACH) qui procure une distinction tinctoriale des colonies de salmonelles.Les rĂ©sultats mettent en Ă©vidence les imperfections de la mĂ©thode traditionnelle (16% de faux nĂ©gatifs) dans l'isolement du pathogĂšne pour l'aliment considĂ©rĂ©. Ils font ressortir l'intĂ©rĂȘt d'y substituer le nouveau protocole (3,1% de faux nĂ©gatifs) dont les avantages de simplicitĂ©, rapiditĂ© et fiabilitĂ© compensent largement le lĂ©ger dĂ©sagrĂ©ment de la technique Ă  savoir un repiquage en milieu sĂ©lectif aprĂšs 6 Ă  8 heures d'incubation.La gĂ©lose Rambach, Ă©lĂ©ment clef de ce gain de temps entre le prĂ©lĂšvement et le diagnostic, s'avĂšre un outil bactĂ©riologique performant en raison des faibles taux de faux positifs (0% dans notre Ă©tude) et faux nĂ©gatifs (1 Ă  2% selon son auteur) engendrĂ©s par des souches atypique
