Selected AbstractsFlow cytometric differential of leukocyte populations in normal bone marrow: Influence of peripheral blood contamination1,CYTOMETRY, Issue 1 2009R. A. Brooimans Abstract Background: Availability of immunophenotypic reference values for the various leukocyte populations distributed in bone marrow may be helpful to recognize abnormal bone marrow development and, therefore, useful as first screening of individuals with suspected hematological malignancies or other hematopoietic disorders. Methods: A single tube four-color staining panel (CD66abce/CD14/CD45/CD34) together with a predefined gating strategy was utilized to immunologically differentiate the distribution of the major leukocyte populations in bone marrow aspirates of healthy donors. The sample-blood erythrocyte ratio was applied to assess the amount of blood contamination of marrow and account for this in the marrow value estimates. Results: The frequency of the major leukocyte populations in bone marrow of 134 normal donors were for granulocytes: mean, 69.4%; SD, 10.3%; monocytes: mean, 4.7%; SD, 2.3%; lymphocytes: mean, 18.3%; SD, 8.7%. The frequency of the immature cell population that included precursor cells of each of the cell lineages among other cell types were mean 5.0%; SD 2.2%. The mean percentage of CD34 positive cells was 1.5%; SD 0.7%. Our results showed further that the frequency of cell populations, of which the presence is restricted to the bone marrow (e.g., CD34+ progenitor cells), is influenced by the degree of peripheral blood admixture. Between the total immature cells and purity of the bone marrow, there was a significant positive correlation demonstrated, whereas a negative correlation was found between the percentages of both lymphocytes as monocytes and the purity of the bone marrow. Conclusions: With a single tube-staining panel, we obtained reference values for flow cytometric assessment of all relevant leukocyte populations present in bone marrow that can be used as a frame of reference for better recognition of individuals with abnormal hematopoiesis. In addition, we have demonstrated the influence of the degree of peripheral blood admixture in the bone marrow aspirates on those reference values. © 2008 Clinical Cytometry Society [source] Investigation of mood-congruent false and true memory recognition in depressionDEPRESSION AND ANXIETY, Issue 1 2005Steffen Moritz Ph.D. Abstract The present study investigated the extent of mood-congruent false and true memory recognition in depression. A group of 25 patients with depression and 28 healthy controls completed a variant of the Deese-Roediger McDermott task. Four lists were read to participants in sequence, followed by a recognition task. The words in each list were associated with a central but unmentioned theme word that was either depression-relevant (i.e., loneliness), delusion-relevant (betrayal), positive (holidays), or neutral (window). Whereas it was expected to replicate the conventional mood-congruent effect in depression (better recognition of depression-relevant items), the available literature did not allow strong predictions to be made on the extent of mood-congruent false recognition in depression. Results showed that depressed patients learned emotionally charged material equally well as healthy participants but forgot significantly more neutral material. A conventional mood-congruent memory bias was not found, but relative to healthy controls, patients with depression committed more false recognition errors for emotionally charged words, particularly for depression-relevant items. The results confirm that depressed patients are biased toward emotional material. Reasons for the absence of the expected mood-congruent memory bias are discussed. It is suggested that researchers as well as clinicians should pay more attention to mood-congruent false recollection, because it may undermine the validity of autobiographic reports in depressive patients and may represent a maintenance factor for the disorder.

[source] Six-Month-Olds' Detection of Clauses Embedded in Continuous Speech: Effects of Prosodic Well-FormednessINFANCY, Issue 1 2000Thierry Nazzi Three experiments investigated the role of prosodic structure for infants' recognition of embedded word sequences. Six-month-olds were familiarized with 2 versions of the same sequence, 1 corresponding to a well-formed prosodic unit and the other to a prosodically ill-formed sequence (although a successive word series). Next, infants heard 2 test passages. One included the well-formed unit, and the other included the ill-formed sequence. In Experiment 1, infants listened longer to the passage containing the well-formed unit, suggesting that such units, even when they are embedded, are better recognized. Experiments 2 and 3 showed that this better recognition does not depend on an acoustic match between the familiarized sequences and their later embeddings. This suggests that the advantage of the well-formed unit is at least partially due to infants' use of prosody to parse continuous speech. [source] Medical students' recognition of elder abuseINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 7 2009Jonas Thompson-McCormick Abstract Objectives To determine the proportion of fourth-year medical students who correctly recognise abusive and not abusive care of older people and whether recognition is related to sociodemographic factors and education. Design A cross-sectional self-report questionnaire study, using the Caregiving Scenario Questionnaire; measuring recognition of elder abuse according to the Department of Health's definition. Participants Fourth-year medical students at University College London and the University of Birmingham, UK. Results Two hundred and two of 207 students (97.6%) responded. Twenty-nine of 201 (14.4%) identified accepting someone was not clean; 113/200 (56.5%) locking someone in alone; and 160/200 (80.0%) trapping someone in an armchair as abusive. All medical students correctly identified four out of five not abusive responses. Twelve (6.0%) incorrectly identified camouflaging the door to prevent wandering as abusive. Logistic regression analysis found the independent predictors of recognising that locking in alone was abusive were working as a professional carer (OR,=,3.33, 95% CI,=,1.25,8.89, p,<,0.05) and reporting being taught to look for elder abuse (OR,=,0.46, 95% CI,=,0.24,0.89, p,<,0.05). Similarly, the independent predictors of recognising that restraint in an armchair was abusive were attending university A versus university B (OR,=,2.38, 95% CI,=,1.09,5.26, p,<,0.05); being of White British versus Asian ethnicity (OR,=,4.00, 95% CI,=,1.75,9.09, p,<,0.01). Conclusions Medical students are good at recognising not abusive care, but not as successful at recognising elder abuse. Working as a professional carer was associated with better recognition of abuse, while personal contact with a person with dementia and recalling formal education about abuse were not.

[source] Fear-avoidance beliefs and pain as predictors for low physical activity in patients with leg ulcerPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 3 2009Kirsti Skavberg Roaldsen Abstract Background and Purpose.,Previous studies have shown that patients with chronic venous insufficiency are deconditioned and physically inactive. The present study aimed to examine the occurrence of fear-avoidance beliefs in patients with chronic venous insufficiency, and to investigate the role of fear-avoidance beliefs and pain severity in predicting the low level of physical activity in these patients.,Method.,Data were collected by a postal questionnaire sent to 146 patients with chronic venous insufficiency and current or previous venous leg ulcer. Complete data were collected from 98 patients aged 60,85 years , 63% women , giving a response rate of 67%. Fear-avoidance beliefs were assessed by the Fear-Avoidance Beliefs Questionnaire, physical activity subscale. Pain and physical activity were assessed by the Six-point Verbal Rating Scale of Pain Assessment and the Physical Activity Questionnaire, respectively.,Results.,Fear-avoidance beliefs were present in 81 (83%) of the patients with chronic venous insufficiency (range 0,24, median 12). Forty patients (41%) had strong fear-avoidance beliefs. One-third of the patients with healed ulcers had strong fear-avoidance beliefs. Patients with low physical activity had significantly stronger fear-avoidance beliefs and more severe pain than patients with high physical activity. Multiple logistic regression showed that the odds ratio (OR) for low physical activity were about three times higher for patients with strong fear-avoidance beliefs (OR 3.1, 95% confidence interval 1.1,8.3; p = 0.027) than for patients with weak fear-avoidance beliefs.,Conclusions.,Fear-avoidance beliefs were present in most patients with chronic venous insufficiency and were associated with low physical activity. Clinical implications ought to include a better recognition of fear-avoidance beliefs, early information about the negative consequences of such beliefs, and the importance of physical activity to counteract poor mobility.
