Researchers have established a link between abuse and disability, but most abused individuals do not experience disability. While some survivors are severely harmed by their experiences of abuse, other survivors of similar exposure appear to have no long-term health problems. Can the presence of social capital account for these differences? Cross-sectional data from the Ontario Health Supplement were used to assess the association between child abuse, age, social capital (social connections and disruptions in living circumstances and relationships), cultural capital (education and occupation) and financial capital (money) and disability in a female community sample (n=4238). The results suggest that abuse (physical and sexual) and financial capital are associated with disability, but not social capital. 相似文献

Drugs that lack the ability to cross the blood-brain barrier (BBB) need to be placed directly into the central nervous system. Our laboratory studies the involvement of the glutamatergic system in the aggressiveness of glioma, and some ligands of glutamate receptors cannot permeate the BBB. Here, glioma-implanted rats were treated by a technique that delivers ligands directly into the cerebrospinal fluid by puncture into the cisterna cerebellomedullaris. Rats were anesthetized and fixed in a rodent stereotactic device. The head was gently tilted downwards at an angle that allowed exposure of the cisterna. Injection into the cisterna was done freehand using a gingival needle coupled to a microsyringe. The efficiency of intracisternal injection was demonstrated using a methylene blue solution. This type of injection is adaptable for any rodent model using small volumes of a variety of other drugs, and is an interesting method for neuroscience studies. 相似文献

Nerve growth factor (NGF) is an important modulator of rat pancreatic β-cell physiology in vitro. In this study, we analysed the expression of NGF, TrkA and insulin in human pancreatic islets from normal, ductal adenocarcinoma and insulinoma-afflicted samples, using double immunofluorescent labelling and confocal microscopy.We found that in normal human pancreas, insulin and NGF are co-expressed in β cells. Moreover, similar to previous observations in rat, the high affinity NGF receptor TrkA is also expressed in β cells.Pancreatic β cells in normal islets from adenocarcinoma and mucinous cystadenocarcinoma patients also expressed NGF. In 2 out of 15 exocrine tumour samples, NGF was detected also in the tissue surrounding the islets, while 2 out of 13 adenocarcinoma tumours expressed this growth factor.In five insulinoma samples, we observed weaker immunofluorescent labelling of insulin and NGF in the neoplastic tissue, compared to the islets not afflicted by the tumour, which may be a consequence of increased hormone secretion rate.We demonstrate that human β cells express TrkA and NGF. These findings are consistent with the hypothesis that NGF modulates insulin secretion through a paracrine/autocrine loop, similar to the one observed in cultured rat β cells. 相似文献

Serum samples from 55 patients with systemic lupus erythematosus (SLE) were selected for the absence of anti-extractable nuclear antigen antibodies after routine immunodiffusion tests. These sera were immunoblotted for anti-Sm and anti-RNP antibodies on a HeLa cell nuclear extract. Ten (18%) were negative and 45 (82%) produced complex patterns: 10 (18%) suggestive of anti-Sm, three (5%) anti-RNP, and 32 (58%) a combination of anti-Sm and anti-RNP antibodies. These data were very similar to those obtained from sera from a control group of 28 SLE sera selected for positivity of anti-Sm and anti-RNP precipitins with the immunodiffusion test. IgM isotype antibodies to the D peptide were significantly more prevalent than IgG isotype antibodies, whereas antibodies to the 68 kD polypeptide were of both IgM and IgG isotypes. Sera with an anti-Sm/RNP immunoblotting pattern stemmed from a group of patients with SLE with a higher titre of anti-dsDNA antibodies. Among clinical symptoms, the incidence of haemolytic anaemia was higher in the group of patients with the anti-Sm immunoblotting profile. Patients with an anti-RNP immunoblotting profile showed a higher incidence of cutaneous symptoms. It is concluded that immunoblotting for anti-Sm or anti-RNP antibody determination is a very sensitive diagnostic tool in patients with SLE. 相似文献

Objective
The objective was to investigate impulsiveness among chronic hepatitis C (CHC) patients and its association with sociodemographic, clinical and psychopathological factors.Method
Ninety-one CHC individuals were enrolled in a cross-sectional study at a Brazilian public university-based outpatient’s service for infectious diseases. They were assessed using the Barrat Impulsiveness Scale, Brief Fatigue Inventory, Beck Depression Inventory and Hamilton Anxiety Scale. Structured psychiatric interview was performed according to the Mini International Neuropsychiatric Interview. Multivariate analysis was performed according to linear stepwise forward regression.Results
The total score of impulsiveness according to BIS in studied population was 64.6±9.8. The scores for the nonplanning, cognitive–attentional and motor domains were 23.8±5, 19.4±2.9 and 21.4±5, respectively. Impulsiveness was associated with lower educational level, current interferon-α (IFN) use, attention-deficit/hyperactivity disorder, alcohol use disorder, mixed anxiety and depressive disorder, specific phobia, bipolar spectrum disorders and anxiety symptoms. During IFN treatment, impulsiveness was also associated with suicide risk.Conclusion
Impulsiveness was frequent in CHC patients and was associated with several psychopathological alterations. Impulsiveness management should be considered when attending CHC patients. 相似文献9.

BackgroundAtopic dermatitis (AD) is a chronic inflammatory skin disease leading to substantial quality of life impairment with heterogeneous treatment responses. People with AD would benefit from personalised treatment strategies, whose design requires predicting how AD severity evolves for each individual.ObjectiveThis study aims to develop a computational framework for personalised prediction of AD severity dynamics.MethodsWe introduced EczemaPred, a computational framework to predict patient‐dependent dynamic evolution of AD severity using Bayesian state‐space models that describe latent dynamics of AD severity items and how they are measured. We used EczemaPred to predict the dynamic evolution of validated patient‐oriented scoring atopic dermatitis (PO‐SCORAD) by combining predictions from the models for the nine severity items of PO‐SCORAD (six intensity signs, extent of eczema, and two subjective symptoms). We validated this approach using longitudinal data from two independent studies: a published clinical study in which PO‐SCORAD was measured twice weekly for 347 AD patients over 17 weeks, and another one in which PO‐SCORAD was recorded daily by 16 AD patients for 12 weeks.ResultsEczemaPred achieved good performance for personalised predictions of PO‐SCORAD and its severity items daily to weekly. EczemaPred outperformed standard time‐series forecasting models such as a mixed effect autoregressive model. The uncertainty in predicting PO‐SCORAD was mainly attributed to that in predicting intensity signs (75% of the overall uncertainty).ConclusionsEczemaPred serves as a computational framework to make a personalised prediction of AD severity dynamics relevant to clinical practice. EczemaPred is available as an R package. 相似文献

This study examines the association between nutrient and fiber intake and the risk of renal cell carcinoma (RCC). Between 1994 and 1997 in 8 Canadian provinces, mailed questionnaires were completed by 1,138 incident, histologically confirmed cases of RCC and 5,039 population controls. Measurement included information on socioeconomic status, lifestyle habits, and diet. A 69-item food frequency questionnaire provided data on eating habits 2 yr before data collection. Odds ratios (ORs) and 95% confidence intervals were derived through unconditional logistic regression. Intakes of total fat, saturated fat, monounsaturated fat, trans-fat, and cholesterol were associated with the risk of RCC; the ORs for the highest vs. the lowest quartile were 1.67, 1.53 and 1.46, 1.31, and 1.48, respectively. The positive association was apparently stronger in women, overweight or obese, and never smokers. Sucrose was related to the risk of RCC. High fiber intake was inversely associated with RCC risk. No association was found with intake of total protein and polyunsaturated fat, n-3 and n-6 polyunsaturated fatty acids, and total carbohydrates. The results were consistent across strata of sex, tobacco, and BMI. The findings suggest that a diet low in fats and cholesterol and rich in fiber could favorably affect the risk of RCC. 相似文献
