Objective: To monitor key processes and outcomes in joint health and social services community psychogeriatric teams. Design: Six month follow-up of new referrals to 4 teams in Cambridge. Data collected from structured clinical assessment forms at baseline and interviews with keyworkers at follow-up. Data for groups with and without dementia were compared. Setting: Two rural and two urban teams in area with relatively large long stay inpatient facility but low independent sector provision. All were routine service teams, rather than run for research purposes. Main outcome measures: The main outcome measures were survival, institutionalisation, key worker assessments of avoidable admissions, appropriateness of placement, unmet needs, carer stress and global outcome for patient and carers. Results: Rates of referral to urban teams were double rural rates. Around forty percent of the dementia group had a social worker as assessor and keyworker. The dementia group was significantly more dependent and received more informal and formal care. After six months, only 54% of the dementia group were alive and living outside institutional care, compared to 79% in the functionally ill group. Unplanned admissions to hospitals or homes were rarely judged avoidable by keyworkers. Outcomes for carers were judged poor in 15% of both groups, and 13% and 11% of carers respectively were judged to be under severe stress. Unmet needs were more common in the dementia group, and related principally to residential care and carer respite. A number of measures, including evidence of geographical inequity and identification of unmet needs, provided an important contribution to local policy development. Further work is needed on the validity of keyworker assessments of carer stress, given the findings of the carer interview sub-study. 相似文献

Pooling neural imaging data across subjects requires aligning recordings from different subjects. In magnetoencephalography (MEG) recordings, sensors across subjects are poorly correlated both because of differences in the exact location of the sensors, and structural and functional differences in the brains. It is possible to achieve alignment by assuming that the same regions of different brains correspond across subjects. However, this relies on both the assumption that brain anatomy and function are well correlated, and the strong assumptions that go into solving the under‐determined inverse problem given the high‐dimensional source space. In this article, we investigated an alternative method that bypasses source‐localization. Instead, it analyzes the sensor recordings themselves and aligns their temporal signatures across subjects. We used a multivariate approach, multiset canonical correlation analysis (M‐CCA), to transform individual subject data to a low‐dimensional common representational space. We evaluated the robustness of this approach over a synthetic dataset, by examining the effect of different factors that add to the noise and individual differences in the data. On an MEG dataset, we demonstrated that M‐CCA performs better than a method that assumes perfect sensor correspondence and a method that applies source localization. Last, we described how the standard M‐CCA algorithm could be further improved with a regularization term that incorporates spatial sensor information.

For the application of bone marrow stromal cells (BMSCs) in cartilage tissue engineering, it is imperative to develop efficient strategies for their chondrogenic differentiation. In this study, the conditioned media derived from chondrocyte/scaffold constructs were used to direct chondrogenic differentiation of BMSCs. The porcine articular chondrocytes were seeded on the PGA/PLA scaffolds to form chondrocyte/scaffold constructs and were cultured to form engineered cartilage in vitro. The culture media were collected as conditioned media and used for chondrogenic induction of BMSC pellets (experimental group, Exp.). The chondrocyte pellets and BMSC pellets were cultured routinely as positive control (PC) and negative control (NC), respectively. After 4 weeks, the wet weight and GAG content in Exp. group and PC group were significantly higher than that in NC group. Histological and immunohistochemical analysis showed that cartilaginous tissue was formed with typical cartilage lacuna structure and positive staining of collagen Type II (Col II) in the peripheral area of the BMSC pellets in Exp. group. Gene expression of Sox9, Col II, and COMP in Exp. group and PC group were significantly higher than that in NC group. The growth factors in the conditioned media derived from human costal chondrocytes‐scaffold constructs were tested by protein microassay. The conditioned media contained low levels of TGF‐β1,2,3, IGF‐1 and high levels of IGF‐2, FGF‐4, and IGFBP4,6, and so forth. The soluble factors derived from the engineered cartilage can induce chondrogenic differentiation of BMSCs independently. Many cytokines may function in chondrogenesis in a coordinated way.

Mast cells play a central role in inflammatory and allergic reactions by releasing inflammatory mediators through 2 main pathways, immunoglobulin E‐dependent and E‐independent activation. In the latter pathway, mast cells are activated by a diverse range of basic molecules (collectively known as basic secretagogues) through Mas‐related G protein‐coupled receptors (MRGPR s). In addition to the known basic secretagogues, here, we discovered several endogenous protein and enzyme fragments (such as chaperonin‐10 fragment) that act as bioactive peptides and induce immunoglobulin E‐independent mast cell activation via MRGPRX 2 (previously known as MrgX2), leading to the degranulation of mast cells. We discuss the possibility that MRGPRX 2 responds various as‐yet‐unidentified endogenous ligands that have specific characteristics, and propose that MRGPRX 2 plays an important role in regulating inflammatory responses to endogenous harmful stimuli, such as protein breakdown products released from damaged or dying cells. 相似文献
