Mice transgenic with the human poliovirus receptor gene develop clinical signs and neuropathology similar to those of human poliomyelitis when neurovirulent polioviruses are inoculated into the central nervous system (CNS). Factors contributing to disease severity and the frequencies of paralysis and mortality include the poliovirus strain, dose, and gender of the mouse inoculated. The more neurovirulent the virus, as defined by monkey challenge results, the higher the rate of paralysis, mortality, and severity of disease. Also, the time to disease onset is shorter for more neurovirulent viruses. Male mice are more susceptible to polioviruses than females. TGM-PRG-3 mice have a 10-fold higher transgene copy number and produce 3-fold more receptor RNA and protein levels in the CNS than TGM-PRG-1 mice. CNS inoculations with type III polioviruses differing in relative neurovirulence show that these mouse lines are similar in disease frequency and severity, demonstrating that differences in receptor gene dosage and concomitant receptor abundance do not affect susceptibility to infection. However, there is a difference in the rate of accumulation of clinical signs. The time to onset of disease is shorter for TGM-PRG-3 than TGM-PRG-1 mice. Thus, receptor dosage affects the rate of appearance of poliomyelitis in these mice. 相似文献
The Coping Inventory for Stressful Situations (CISS; Endler & Parker, 1990) is a self-report measure of Emotion-, Task-, and Avoidance-oriented coping. The psychometric properties of the CISS were evaluated in a large sample of outpatients with major depressive disorder (N = 298). The CISS scales demonstrated good reliability and support for their factorial validity was obtained. Relationships between the CISS scales and the broad personality domains from the five-factor model of personality, as well as two measures of emotional distress, were examined. Less-adaptive coping strategies (i.e., Emotion-oriented coping) were associated with less-adaptive personality traits (i.e., Neuroticism) and with psychological distress (i.e., Depression), whereas the reverse was found regarding adaptive coping strategies (i.e., Task-orientated coping). The incremental validity of the CISS was demonstrated by multiple-regression analyses that found two CISS scales accounted for significant variance in psychological distress beyond that contributed by the demographic and personality variables. 相似文献
Background: Measurement of the quality of health care is essential for quality improvement, and patients are an underused source of data about quality of care. We describe the adaptation of a set of USA quality indicators for use in patient interview surveys in England, to measure the extent to which older patients receive a broad range of effective healthcare interventions in both primary and secondary care.
Method: One hundred and nineteen quality indicators covering 16 clinical areas, based on a set of indicators for the care of vulnerable elderly patients in the USA, were reviewed by a panel of 10 clinical experts in England. A modified version of the RAND/UCLA appropriateness method was used and panel members were supplied with literature reviews summarising the evidence base for each quality indicator. The indicators were sent for comment before the panel meeting to UK charitable organisations for older people.
Results: The panel rated 102 of the 119 indicators (86%) as valid for use in England; 17 (14%) were rejected as invalid. All 58 indicators about treatment or continuity and follow up were rated as valid compared with just over half (13 of 24) of the indicators about screening.
Conclusions: These 102 indicators are suitable for use in patient interview surveys, including the English Longitudinal Study of Ageing (ELSA). The systematic measurement of quality of care at the population level and identification of gaps in quality is essential for quality improvement. There is potential for transfer of quality indicators between countries, at least for the health care of older people.
Aim: Most national guidelines recommend psychological therapy for people with first‐episode psychosis (FEP) but interventions proven effective in randomized control trials (RCTs) conducted in research settings do not always translate effectively to real‐world clinical environments. In a limited health system, it is important to understand the system and patient barriers to participation in effective treatment. We sought to determine what patient characteristics influenced clinicians' decision to refer or not to refer to group cognitive behavioural therapy for FEP and what characteristics were associated with those referred attending/not attending and adhering/not adhering to the programme. Methods: Between 2006 and 2008, all cases of confirmed FEP from a defined geographical region were examined using the Structured Clinical Interview for DSM‐IV‐TR Axis I Disorders for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV) diagnoses, the Scale for Assessment of Positive Symptoms, Scale for Assessment of Negative Symptoms, Calgary Depression Scale for Schizophrenia and Birchwood Insight Scale. Duration of untreated psychosis was established using the Beiser Scale. Results: Of the 124 (77 males, 47 females) people in the final sample, 88 (72%) were referred for cognitive behavioural therapy (CBT), 52 (59%) attended and 12 (23%) did not complete CBT. Those with higher levels of insight into the need for treatment (U = 740.00, z = −2.63, P = 0.008) and higher levels of positive symptoms (t (120) = −3.064, P = 0.003) were more likely to be referred to CBT. Those with higher educational attainment (χ2 = 9.48, P = 0.03) and fewer negative symptoms, particularly in relation to global attention (t (85) = 2.32, P = 0.03), were more likely to attend and complete CBT. Conclusion: Within an early intervention service for FEP, it appears that individuals with less education, more negative symptoms and less insight experienced significant barriers to successfully completing group CBT. More information for referring clinicians about the benefits of CBT for FEP could help increase referral rates. Assertive outreach for people at risk of disengaging or non‐adherence should also be considered. 相似文献
