Different studies of long‐term chondrocytes viability have shown a gradual reduction as a function of time and ambient temperature. The aim of our in vitro study was to establish chondrocyte postmortem viability curves for 4°C, 11°C, 23°C, 35°C during 63 days after the donors' death. Osteochondral cylinders were procured from the knees of 16 male donors (20–47 years), stored in preservation media that was not changed, and analyzed in 3‐day intervals using a confocal laser scanning microscope. A significant influence of time on viability was found from Day 9 (p = 0.0029) and onwards (p < 0.0001). The lowest overall chondrocyte viability was at 35°C, followed by 4°C (p < 0.0001). The conditions used in this in vitro analysis suggest that similar viabilities may occur while in situ in the decedent. Further studies of chondrocyte viability from individuals with known postmortem intervals may show premise to help evaluate time since death in the late postmortem interval. 相似文献

Health inequalities are high among offending groups. The comprehensive health assessment tool (CHAT) is a semi-structured assessment developed to provide a standardised approach to health screening for all young offenders admitted to the secure estate. The four sections of the CHAT (physical health, mental health, substance misuse and neurodisability) were evaluated within a two-phased study of male adolescents (aged 15–18?years) within a young offenders institution in the north-west of England. Within Phase 1, a consecutive sample of 127 new receptions was assessed using the physical health, mental health and substance misuse sections of the CHAT against a range of reference standard assessments. Phase 2 of the study evaluated the neurodisability section on 93 male adolescents against reference standard tools. The four sections of the CHAT demonstrated fair to good convergent validity when compared against reference standard tools in male offenders. The diagnostic accuracy rate was 76% for mental health, 63% for physical health, 83% for substance misuse and 53% for neurodisability when compared against reference standard assessment tools. The introduction of the CHAT offers the opportunity to enhance existing reception screening practices and create an integrated approach to the assessment of health needs across the secure estate. 相似文献

Screening for mental health problems on reception into custody has been criticised. However, there have been few studies on care pathways through custody as a result of screening identification. We aimed to identify what actions were taken as a result of screening positive for suicidal ideation and mental health problems. Case records for 2166 prisoners newly received into five prisons in England and documented contact with health care professionals in the following month were examined by hand over a four-month period. Altogether, 3% of prisoners were screened as having current suicidal ideas, of whom 30% had no contact with mental health services or risk assessment documentation. Another 21% of new receptions received psychotropic medication, for whom over 60% received no primary mental health assessment, and only 36% received psychotropic medication in prison. Care pathways need to be defined, and screening needs to be delivered as originally intended by initial screen for life-threatening matters, followed by a later, comprehensive assessment of health needs. 相似文献

Abstract: Most studies of long‐term chondrocytes survival were for tissue banks. They showed a gradual reduction in the viable chondrocytes percentage as a function of time and ambient temperature, but the samples were harvested under optimal conditions. The aim of our study was to determine the most reliable combination of cartilage source and assay for the in vitro postmortem chondrocyte viability analysis in the conditions that imitate a dead body. Osteochondral cylinders were procured from femoral condyles and talar trochleas of three male donors and stored in the cell culture media at 4 ± 2°C and 23 ± 2°C. The samples were analyzed by a cell viability analyzer and a confocal laser scanning microscope (CLSM) initially 24–36 h after death and then in 4‐week intervals. The results reconfirmed the significant influence of time (p = 0.0002), but not of the temperature (p = 0.237). The largest reproducibility was presented for the knee joint and the CLSM. 相似文献

This is a progress report on the development of practical methods for the actuarial prediction of violence. The literature indicates that actuarial prediction is more accurate than clinical prediction, but in practice actuarial methods seem to be used rarely. Here we address two obstacles to the clinical use of actuarial prediction methods. First, clinicians may be averse to actuarial methods that require calculations. To remedy this, we developed a regression tree screen that presents actuarial information about violence in a series of yes/no questions. Second, using actuarial methods to identify the small minority of violent patients in a general psychiatric population may be too costly. To remedy this, we developed a method to prescreen patients for intensive evaluation using an inexpensive assessment. We evaluated regression trees and two-stage screening by comparing their accuracies against conventional actuarial methods. The results showed that actuarial predictions based on regression trees and two-stage screens were as accurate as regression-based methods in identifying repetitively violent patients. These easier-to-use methods may therefore be useful techniques for actuarial predictions. 相似文献
