Participation of the elderly after vision loss

Purpose. To assess the degree of participation of the visually impaired elderly and to make a comparison with population-based reference data. Method. This cross-sectional study included visually impaired elderly persons (≥55 years; n = 173) who were referred to a low-vision rehabilitation centre. Based on the International Classification of Functioning, Disability and Health (ICF) participation in: (1) domestic life, (2) interpersonal interactions and relationships, (3) major life areas, and (4) community, social and civic life was assessed by means of telephone interviews. In addition, we assessed perceived participation restrictions. Results. Comparison with reference data of the elderly showed that visually impaired elderly persons participated less in heavy household activities, recreational activities and sports activities. No differences were found for the interpersonal interactions and relationships domain. Participants experienced restrictions in household activities (84%), socializing (53%), paid or voluntary work (92% ), and leisure activities (88%). Conclusions. Visually impaired elderly persons participate in society, but they participate less than their peers. They experience restrictions as a result of vision loss. These findings are relevant, since participation is an indicator for successful aging and has a positive influence on health and subjective well-being. © 2010 Informa UK, Ltd

ROM in de volwassenenpsychiatrie: een evaluatie van meetinstrumenten

An evaluation of the most commonly used ROM measures in Dutch psychiatry is lacking, both for severe mental illnesses and for common psychiatric disorders. To provide an overview of the characteristics and quality of outcome measures. A literature study yielded six outcome measures. The psychometrical, clinical and practical aspects of these scales are described. The measures are suitable and are of adequate quality. It remains to be seen if any of the outcome measures are suitable for both serious and less serious mental illnesses. The use of a combination of a self-rating scale and an observerrating scale that measure symptoms and domains of functioning may be the most promising choic

Pure compared with mixed serous endometrial carcinoma: two different entities?

Item does not contain fulltextOBJECTIVE: : To analyze whether mixed compared with pure uterine papillary serous carcinoma histology affects clinical outcome, and to assess uterine papillary serous carcinoma for its association with the precursor lesion endometrial intraepithelial carcinoma. METHODS: : A multi-institution observational study of stage I-IV uterine papillary serous carcinoma patients was performed. Histopathologic slides were reviewed by four expert pathologists, with determination of the percentage serous histology within each tumor. The pre-existent endometrium was evaluated for the presence of endometrial intraepithelial carcinoma. RESULTS: : We included 108 uterine papillary serous carcinoma patients. Fifty-eight patients had mixed and 50 patients had pure uterine papillary serous carcinoma histology. On multivariable analysis, advanced International Federation of Gynecology and Obstetrics (FIGO) stage (hazard ratio [HR] 3.15, 95% confidence interval [CI] 1.57-6.32), mixed uterine papillary serous carcinoma histology (HR 0.35, 95% CI 0.19-0.66), and lymphovascular space invasion (HR 2.10, 95% CI 1.07-4.16) were significantly associated with recurrence. International Federation of Gynecology and Obstetrics stage (HR 4.67, 95% CI 2.25-9.70) and mixed uterine papillary serous carcinoma histology (HR 0.39, 95% CI 0.20-0.76) were significantly and independently associated with survival. Endometrial intraepithelial carcinoma was identified in 83.9% of all cases, with no significant difference between mixed and pure uterine papillary serous carcinoma patients. Atrophic or weakly proliferative endometrium was found in 90.7% of pure uterine papillary serous carcinoma cases, whereas hyperplastic endometrium with atypia was more commonly found in 34.7% of mixed carcinoma patients with uterine papillary serous carcinoma (P=.004). CONCLUSION: : Pure uterine papillary serous carcinoma histology and FIGO stage are the most important risk factors for recurrence and survival in patients with uterine papillary serous carcinoma. Adjusted for covariates, patients with pure uterine papillary serous carcinoma had a 2.9-times greater risk for recurrence and a 2.6-times higher risk of death compared with patients with mixed uterine papillary serous carcinoma. Furthermore, endometrial intraepithelial carcinoma was equally found among pure and mixed uterine papillary serous carcinoma cases, whereas the nonneoplastic endometrium was atrophic or weakly proliferative in pure uterine papillary serous carcinoma cases compared with more hyperplastic endometrium with atypia in mixed uterine papillary serous carcinoma cases.

Small cell carcinoma of the lung and large cell neuroendocrine carcinoma interobserver variability

Aims: To test the hypothesis that the published morphological criteria permit reliable segregation of small cell carcinoma of the lung (SCLC) and large cell neuroendocrine carcinoma (LCNEC) cases by determining the interobserver variation. Methods and results: One hundred and seventy cases of SCLC, LCNEC and cases diagnosed as neuroendocrine lung carcinoma before LCNEC had been established as a diagnostic category were retrieved from the archives of the assessor's institutes. A representative haematoxylin and eosin section from each case was selected for review. Batches of cases were circulated among nine pathologists with a special interest in pulmonary pathology. Participants were asked to classify the cases histologically according to the 2004 World Health Organization (WHO) criteria. The diagnoses were collected and kappa values calculated. Unanimity of diagnosis was achieved for only 20 cases; a majority diagnosis was reached for 115 cases. In 35 cases no consensus diagnosis could be reached. There was striking variability amongst assessors in diagnosing SCLC and LCNEC. The overall level of agreement for all cases included in this study was fair (kappa = 0.40). Conclusions: Using non-preselected cases, the morphological WHO criteria for diagnosing SCLC and LCNEC leave room for subjective pathological interpretation, which results in imprecise categorization of SCLC and LCNEC cases

Gene signature fingerprints stratify SLE patients in groups with similar biological disease profiles: a multicentre longitudinal study

OBJECTIVES: Clinical phenotyping and predicting treatment responses in SLE patients is challenging. Extensive blood transcriptional profiling has identified various gene modules that are promising for stratification of SLE patients. We aimed to translate existing transcriptomic data into simpler gene signatures suitable for daily clinical practice. METHODS: Real-time PCR of multiple genes from the IFN M1.2, IFN M5.12, neutrophil (NPh) and plasma cell (PLC) modules, followed by a principle component analysis, was used to identify indicator genes per gene signature. Gene signatures were measured in longitudinal samples from two childhood-onset SLE cohorts (n = 101 and n = 34, respectively), and associations with clinical features were assessed. Disease activity was measured using Safety of Estrogen in Lupus National Assessment (SELENA)-SLEDAI. Cluster analysis subdivided patients into three mutually exclusive fingerprint-groups termed (1) all-signatures-low, (2) only IFN high (M1.2 and/or M5.12) and (3) high NPh and/or PLC. RESULTS: All gene signatures were significantly associated with disease activity in cross-sectionally collected samples. The PLC-signature showed the highest association with disease activity. Interestingly, in longitudinally collected samples, the PLC-signature was associated with disease activity and showed a decrease over time. When patients were divided into fingerprints, the highest disease activity was observed in the high NPh and/or PLC group. The lowest disease activity was observed in the all-signatures-low group. The same distribution was reproduced in samples from an independent SLE cohort. CONCLUSIONS: The identified gene signatures were associated with disease activity and were indicated to be suitable tools for stratifying SLE patients into groups with similar activated immune pathways that may guide future treatment choices

Efficient Light Emission from Hexagonal SiGe

Silicon and Germanium have an indirect band gap, which limits their use in optoelectronic devices. Here, we show that we can create a direct band gap in Si 1-x Ge x alloys by changing the crystal structure from cubic to hexagonal. DFT calculations predict a strong optical transition for 0.651-x Ge x alloys have been fabricated and efficient light emission has been observed
