Intentional Communication of Young Children with Autism Spectrum Disorder: Judgments of Different Communication Partners

The purpose of this study was to examine judgments made by different listeners of the communicative intent, specifically requesting and rejecting, of young children with autism and limited expressive language. Video clips from a structured assessment study of three young children with autism spectrum disorder were edited and viewed by adult raters from four subgroups. Analysis of the findings indicated that those who were both familiar and expert were more accurate and more confident in their judgments than those who were unfamiliar and non-expert. There was more variation among the four subgroups of raters in accuracy related to rejecting compared to requesting behavior. It was concluded that collaboration in the determination of intention and consistency of responding to specific communicative forms among all individuals who are involved in the child’s life appear to be important steps in developing common communication goals.     

Establishment and characterization of 7 ovarian carcinoma cell lines and one granulosa tumor cell line: Growth features and cytogenetics

The characteristics of 7 newly established ovarian carcinoma cell lines and one granulosa tumor cell line obtained from tumor samples of 7 patients with varying histology of the primary tumor are reported. The cell lines were isolated from 5 serous carcinomas, a mucinous carcinoma, an endometrioid carcinoma and a granulosa cell tumor. All cell lines were passaged at least 25 times and showed stable growth rates. Colony-forming efficiency varied on plastic from 2 to 57% and in agar from 0.01 to 9.30%. The DNA index of the granulosa tumor cell line was diploid, while the ovarian carcinoma cell lines were all aneuploid. In 2 cell lines polyploidisation occurred during culturing. A thorough cytogenetic analysis of 7 cell lines revealed that the granulosa tumor cell line has only minor cytogenetic abnormalities (+5, 22_q+). In contrast, the epithelial ovarian-cancer cell lines gave very complex karyotypes with numerous markers and structurally rearranged chromosomes. The chromosomes most often in excess were 15 and 20. Structural rearrangements of chromosomes 1, 3, 7 and 11 were prominent in all ovarian cell lines. In addition, we found changes in chromosomes X, 5, 8 and 13 that have rarely been described before.     

Poor mental and physical health differentially contributes to disability in hospitalized geriatric patients of different ages

OBJECTIVE: To evaluate the relationship between depressive symptoms, cognition and somatic diseases on functional status of geriatric patients at hospital discharge. METHOD: Patients 65+ years consecutively admitted to the acute care geriatric ward of the Internal Medicine Department I, Civil Hospital of Brescia, Italy, from February 1998 to December 2000 (n = 830) were examined. Functional disability was defined as need of physical assistance in at least one of the basic Activities of Daily Living (ADL). The Greenfield Index of Disease Severity (IDS) and the Geriatric Index of Comorbidity (GIC) were used to measure number and severity of diseases. The Mini-Mental State Examination (MMSE) assessed cognitive status and the Geriatric Depression Scale (GDS) measured depressive symptoms. RESULTS: Prevalence of functional disability at discharge was 29.3% in the younger age group (65-74 years) and 55.2% in the older age group (75+ years). Using logistic regression models, older age, poorer cognitive status, and depressive symptoms were independently associated with functional disability in the younger and older age group, respectively. Additionally cognitive impairment and depressive symptoms showed an additive association with disability, especially in younger patients, while comorbidity was correlated with functional status only in the oldest old, in particular among those who were cognitively impaired. CONCLUSION: Functional disability after acute hospitalization is highly prevalent in geriatric patients. Depressive symptoms, comorbidity, and cognitive impairment often coexist, interact and are differentially associated with function depending on age. Considering that depressive symptoms are a modifiable problem, their detection in hospital settings may help clinicians in targeting subjects at high risk of functional disability.     

The magnitude of dementia occurrence in the world

In this study, the worldwide occurrence of dementia in 2000 and during the period 1950-2050 was estimated. The calculations were based on worldwide demographics of the elderly and age-specific prevalence and incidence values of dementia, estimated from a meta-analysis. In a sensitivity analysis, different prevalence sources were used. The worldwide number of persons with dementia in 2000 was estimated at about 25 million persons. Almost half of the demented persons (46%) lived in Asia, 30% in Europe, and 12% in North America. Fifty-two percent lived in less developed regions. About 6.1% of the population 65 years of age and older suffered from dementia (about 0.5% of the worldwide population) and 59% were female. The number of new cases of dementia in 2000 was estimated to be 4.6 million. The forecast indicated a considerable increase in the number of demented elderly from 25 million in the year 2000 to 63 million in 2030 (41 million in less developed regions) and to 114 million in 2050 (84 million in less developed regions). In conclusion, the majority of demented elders live in less developed regions, and this proportion will increase considerably in the future.     

B-1a B cells that link the innate and adaptive immune responses are lacking in the absence of the spleen

Splenectomized individuals are prone to overwhelming infections with encapsulated bacteria and splenectomy of mice increases susceptibility to streptococcal infections, yet the exact mechanism by which the spleen protects against such infections is unknown. Using congenitally asplenic mice as a model, we show that the spleen is essential for the generation of B-1a cells, a B cell population that cooperates with the innate immune system to control early bacterial and viral growth. Splenectomy of wild-type mice further demonstrated that the spleen is also important for the survival of B-1a cells. Transfer experiments demonstrate that lack of these cells, as opposed to the absence of the spleen per se, is associated with an inability to mount a rapid immune response against streptococcal polysaccharides. Thus, absence of the spleen and the associated increased susceptibility to streptococcal infections is correlated with lack of B-1a B cells. These findings reveal a hitherto unknown role of the spleen in generating and maintaining the B-1a B cell pool.
