OBJECTIVE: This longitudinal study was designed to assess the effect of an educational training package for primary health care teams in accident prevention for older people, with reference to the incidence of accidents and their associated economic consequence. METHODS: Nineteen general practices in the West Midlands serving a population of 138 397 were allocated randomly at the practice level either to receive training or continue normal practice. Study data was collated from the initial telephone call, reporting an accident, to the surgery, advice/treatment given at the practice and/or the community, casualty, inpatient care, written correspondence to the patient's GP and any subsequent follow-up visits for accidents to people aged 65 years or older. RESULTS: One thousand, six hundred and sixty-six (8.2%) patients aged 65 years or older registered with the participating practices experienced one accident or more, costing the NHS pound 1.4 million. Extrapolated nationally, annual costs to the NHS for accidents to older people amount to pound 568 million. The educational package had no significant impact on the incidence of accidents. A paucity of general safety advice was given [48 (1.8%) occasions]. CONCLUSIONS: Budgets are being eroded and patients are suffering unnecessarily due to lack of accident prevention advice. This should be considered a priority within the primary health care team. Educational packages alone do not appear to be a cost-effective approach to accident prevention in primary care. 相似文献

BACKGROUND: Hip dislocation in children with cerebral palsy has a well-documented history and morbidity. OBJECTIVE: This paper presents a retrospective study of children with bilateral cerebral palsy who had various postural management and its effect on hip deformity. The most widely accepted theoretical model of hip subluxation/dislocation is that an imbalance in muscle length and strength around the hip leads to acetabular dysplasia and consequent hip subluxation. Maintenance of muscle length and strength and loadbearing is therefore a logical prevention. Research on normal infants' postures has provided biomechanical data to form the theoretical basis of 24 h postural management equipment. METHODS: The notes and X-rays of 59 children with bilateral cerebral palsy from East and West Sussex and Oxfordshire were examined and measured to determine whether a relationship existed between postural management and the level of hip subluxation/dislocation. X-rays were measured using Reimers' hip migration percentage. Postural management support was divided into three groups for analysis. Category 1: use of a 24-h postural management approach using Chailey Adjustable Postural Support (CAPS) systems in lying, sitting and standing; category 2: two items of CAPS (either lying/sitting or sitting/standing supports); category 3: use of the CAPS seat only and/or any other postural supports. Hip status was recorded for analysis as both hips safe (under 33% migrated), or one/both hips subluxed. RESULTS: Children using 'All CAPS' before hip subluxation maintained significantly more hip integrity than other groups (chi2 P < 0.05). CONCLUSIONS: Postural management interventions have an important role in the prevention of hip dysplasia. 相似文献

Possible transient adaptive response to mitomycin C in peripheral lymphocytes from thyroid cancer patients after iodine-131 therapy 总被引:1,自引:0,他引:1

Our study attempted to assess the possible induction and persistence of an adaptive response in lymphocytes of thyroidectomized thyroid cancer patients treated with 131I (2,590 MBq, corresponding to whole body doses in the range of 200-300 mGy), to a testing dose of mitomycin C (MMC) in vitro. The cytogenetic endpoint studied was the induction of micronuclei in cytokinesis-blocked peripheral blood lymphocytes, immediately before treatment and 1, 6 and 24 months after therapy. One month after therapy, induction of micronucleated cytokinesis-blocked lymphocytes ( per thousand ) by MMC was lower (34.6 +/- 7.7) than before therapy (52.1 +/- 5.0). In 7 of 11 patients this reduction was significant. However, at 6 months, induction of micronuclei was markedly higher (133.1 +/- 13.6). This significant increase was observed regardless of the decrease at 1 month. At 24 months, the frequency of micronucleated cells decreased (84.8 +/- 5.5), but remained higher than before treatment. The results obtained 1 month after therapy could reflect adaptation due to radiation, or a higher rate of early apoptosis or cell death, with bone marrow suppression, visible as a lower response in vitro towards MMC. At 6 months, recovery of the lymphocyte population may occur, and higher responses to MMC in vitro could reflect higher chromosomal instability in the previously irradiated stem cells with a concomitant disappearance of adaptation, whereas at 24 months the results show a tendency to return to pretherapy values. 相似文献

AIMS AND BACKGROUND: Carcinoembryonic antigen (CEA) belongs to a family of cell surface glycoproteins. Its level in serum has a significant value for the follow-up and treatment of patients with malignancies. The aim of this study was to correlate the concentration of tumor cytosol CEA (cCEA) with tumor size, patient age and sex, clinical stage, lymph node metastases, and overall survival rate in primary non-small cell lung carcinoma (NSCLC). METHODS AND STUDY DESIGN: The cCEA levels were determined in 76 NSCLC patients by luminescence assay (LIA) and radioimmunoassay (RIA). RESULTS: A strong correlation between LIA and RIA assay results was found (r = 0.992). No correlation was observed between serum CEA and cCEA levels. Tumors smaller than 3 cm had significantly higher cCEA levels than larger tumors, but when a logistic modeling process was applied this difference was not significant (P = 0.038). Histologically well-differentiated tumors also showed a significantly higher expression of cCEA (P <0.05). In addition, patients without lymph node involvement had higher cCEA levels than patients with tumor-positive lymph nodes (P < 0.05). Univariate statistical analysis revealed that the risk of lymph node metastases was 1.8-fold higher in patients with low cCEA levels than in patients with higher levels, taking the median value as cutoff (P = 0.04, Kruskal-Wallis test). CONCLUSIONS: According to the results of our study, patients with overexpression of cCEA may have a better prognosis than those with low cCEA expression. cCEA might therefore be considered a good prognostic parameter as well as a prognostic factor independent of the traditional parameters for lymph node metastases. 相似文献

Fusion proteins created by chromosomal abnormalities are key components of mesenchymal cancer development. The most common chromosomal translocation in liposarcomas, t(12;16)(q13;p11), creates the FUS-CHOP fusion gene. In the past, we generated FUS-CHOP and CHOP transgenic mice and have shown that while FUS-CHOP transgenic develop liposarcomas, mice expressing CHOP, which lacks the FUS domain, display essentially normal white adipose tissue (WAT) development, suggesting that the FUS domain of FUS-CHOP plays a specific and critical role in the pathogenesis of liposarcoma. To test the significance of FUS and CHOP domain interactions within a living mouse, we generated mice expressing the FUS domain and crossed them with CHOP-transgenic mice to generate double-transgenic FUSxCHOP animals. Here we report that expression of the FUS domain restores liposarcoma development in CHOP-transgenic mice. Our results provide genetic evidence that FUS and CHOP domains function in trans for the mutual restoration of liposarcoma. These results identify a new mechanism of tumor-associated fusion genes and might have impact beyond myxoid liposarcoma. 相似文献

Objective: We examined prospectively intakes of vitamins A, C, and E, folate, and specific carotenoids in relation to the risk of basal cell carcinoma of the skin (BCC) in women. Methods: Dietary intake was assessed by food-frequency questionnaires every two–four years and the first diagnosis of BCC was ascertained by self-report every two years. We used logistic regression to model the association between dietary intake and the risk of BCC adjusting for various health, sun exposure, and sun sensitivity factors. Results: During 12 years of follow-up we recorded 5392 cases. We did not find any significant inverse associations between these dietary factors and BCC. On the contrary, weak positive trends were seen with vitamins A, C, and E, and folate. The multivariate relative risks (RRs) comparing the top to bottom quintile were 1.20 (95% CI = 1.10–1.31) for folate, 1.16 (95% CI = 1.06–1.26) for vitamin A, 1.13 (95% CI = 1.03–1.23) for vitamin C, and 1.15 (95% CI = 1.06–1.26) for vitamin E. Exploration of latency periods did not suggest different associations with a particular duration. Conclusions: We did not find evidence that vitamins A, C, and E, and folate, or specific carotenoids play an important protective role against the incidence of BCC. 相似文献

Evidence is accumulating for physical activity as an effective, well-tolerated, highly rewarding complementary behavioral intervention for enhancing quality of life (QOL) as well as fitness among individuals with chronic and even terminal illnesses. However, relatively few studies have examined the feasibility and potential health benefits of supervised, structured exercise programs for sedentary women with primary breast cancer. Forty women over the age of 45 with primary breast cancer participated in a course of group exercise training (GET) delivered in a structured format three times per week for 16 weeks. GET emphasizes physical activities that promote aerobic fitness, strength, and flexibility. Assessments of fitness/vigor and QOL were conducted prior to, during, and upon completion of the program. Results demonstrated that GET was feasible, safe, and well-tolerated. Moreover, the participants experienced significant health benefits over the course of the intervention in multiple dimensions of fitness/vigor (aerobic capacity, strength, flexibility) as well as QOL (increased positive affect, decreased distress, enhanced well-being, and improved functioning). Discussion highlights the need for inclusion of physical activity programs in comprehensive, complementary treatment regimes for breast cancer patients. 相似文献

Oncogenic activation of the RET receptor tyrosine kinase is common in different human cancers. We found that the pyrazolo-pyrimidine PP1 inhibited RET-derived oncoproteins with a half maximal inhibitor concentration of 80 nM. Furthermore, RET/PTC3-transformed cells treated with 5 microM of PP1 lost proliferative autonomy and showed morphological reversion. PP1 prevented the growth of two human papillary thyroid carcinoma cell lines that carry spontaneous RET/PTC1 rearrangements and blocked anchorage-independent growth and tumorigenicity in nude mice of NIH3T3 fibroblasts expressing the RET/PTC3 oncogene. These findings suggest targeting RET oncogenes with PP1 or related compounds as a novel treatment strategy for RET-associated neoplasms. 相似文献

PURPOSE: We report the case of a male newborn with Ohtahara syndrome and right hemimegalencephaly who presented epileptic negative myoclonus in the first days of life. METHODS: Prolonged polygraphic studies were performed, as well as MRI and a full clinical examination. RESULTS: EEG showed a constant and nonreactive pattern of burst suppression. There were several kinds of electro-clinical seizures (generalized myoclonia, short atonias, typical spasm and tonic spasms) at the beginning of the EEG's burst. The periods of EMG silence, lasting less than 300 ms, were associated with stereotyped EEG transients. CONCLUSIONS: Epileptic negative myoclonus can be observed also in neonatal age. The short transient impairment of motor function observed in the newborn seems linked to the slow component of spike-wave discharge, but its mechanism is still not clear. 相似文献

Twenty-four autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) probands were analyzed for the presence of V287L and V287M mutations in the CHRNB2 gene, which have been recently associated with the disease. In all patients, the involvement of the two additional loci reported as being associated with ADNFLE (CHRNA4 gene and chromosome 15q24 region) had been previously excluded. Mutational screening was performed by sequencing a polymerase chain reaction-amplified CHRNB2 DNA fragment, spanning the whole exon 5, which contains the V287L and V287M mutations and codes for approximately 65% of the mature protein. In none of the patients were mutations in the analyzed region of CHRNB2 found. These data, obtained in the largest ADNFLE cohort so far analyzed, demonstrate the rarity of the identified CHRNB2 mutations in ADNFLE patients. 相似文献
