The original 1981 English isolate of avian paramyxovirus type 3 from turkeys was of higher pathogenicity to chickens than the prototype 1968 isolate turkey/Wisconsin. It was lethal to chicks aged one day when given by intravenous or intracerebral inoculation. The age susceptibility was increased to one week by use of an inbred strain or betamethasone. The virus was more pathogenic to its natural host as outbred turkeys aged one week died after intravenous inoculation of the virus and contact transmission resulted in stunting and seroconversion of 2-week-old birds. Monoclonal antibodies to both viral glycoproteins, but not to the two internal proteins, protected one-day-old turkeys from 1000 intravenous LD50 of virus when they were inoculated one day after virus. This was considered to be analogous to maternally derived immunity and emphasised the role of yolk sac antibody in the protection of young stock. 相似文献

Background
Haemodialysis is a life-saving but burdensome therapy for patients with end-stage renal disease, which can substantially impair health-related quality of life (HRQOL) and outcomes. The aim of this study was to determine the patterns of HRQOL and to identify the risk factors for reduced HRQOL in Palestinian patients receiving treatment by haemodialysis.Methods
This cross-sectional study was done between June 15, 2014, and Jan 15, 2015, using the EuroQOL-5 Dimensions instrument (EQ-5D-5L) for the assessment of HRQOL. We approached patients with end-stage renal disease undergoing haemodialysis at inpatient hospitals from ten different settings at a national level. The study protocol was approved by the Ethics Committee of An-Najah National University. Informed verbal consent was obtained from each participant before the start of the interview. Multiple linear regression was used to estimate which variables were significantly associated with reduced HRQOL.Findings
267 (96%) of 277 eligible patients consented to participate. 139 (52%) participants were men, and the mean age was 53·3 years (SD 16·2). 177 (66%) patients had been treated by haemodialysis for less than 4 years. The reported HRQOL, as measured by mean EQ-5D-5L index value, was 0·37 (SD 0·44). We found a moderate positive correlation between the EuroQol-visual analogue scales and the EQ-5D-5L index value (r=0·44; p<0·0001). The results of a multiple linear regression showed a significant association between HRQOL and age (p=0·0011), female sex (p=0·0167), education level (p=0·0057), number of chronic medications (p=0·0493), and number of comorbid diseases (p=0·0001).Interpretation
Our results provide insight into a number of associations between patient variables such as demographics, clinical factors, and their HRQOL. These findings should help raise health-care providers' awareness and improve the quality of life for patients receiving treatment by haemodialysis, especially those who have no formal education, are elderly, are female, are from refugee camps, or have multiple comorbid diseases or chronic medications.Funding

Background
The key to universal coverage in tuberculosis (TB) management lies in community participation and empowerment of the population. Social infrastructure development generates social capital and addresses the crucial social determinants of TB, thereby improving program performance. Recently, there has been renewed interest in the concept of social infrastructure development for TB control in developing countries. This study aims to revive this concept and highlight the fact that documentation on ways to operationalize urban TB control is required from a holistic development perspective. Further, it explains how development of social infrastructure impacts health and development outcomes, especially with respect to TB in urban settings.Methods
A wide range of published Government records pertaining to social development parameters and TB program surveillance, between 2001 and 2011 in Delhi, were studied. Social infrastructure development parameters like human development index along with other indicators reflecting patient profile and habitation in urban settings were selected as social determinants of TB. These include adult literacy rates, per capita income, net migration rates, percentage growth in slum population, and percentage of urban population living in one-room dwelling units. The impact of the Revised National Tuberculosis Control Program on TB incidence was assessed as an annual decline in new TB cases notified under the program. Univariate linear regression was employed to examine the interrelationship between social development parameters and TB program outcomes.Results
The decade saw a significant growth in most of the social development parameters in the State. TB program performance showed 46% increment in lives saved among all types of TB cases per 100,000 population. The 7% reduction in new TB case notifications from the year 2001 to 2011, translates to a logarithmic decline of 5.4 new TB cases per 100,000 population. Except per capita income, literacy, and net migration rates, other social determinants showed significant correlation with decline in new TB cases per 100,000 population.Conclusions
Social infrastructure development leads to social capital generation which engenders positive growth in TB program outcomes. Strategies which promote social infrastructure development should find adequate weightage in the overall policy framework for urban TB control in developing countries. 相似文献9.

Aim
The ability to identify indicators of poor health-related quality of life (HRQoL) is crucial for both improving clinical care and determining targets of intervention for the prevention and treatment of disease. The main objectives of this study were to assess the HRQoL profile of the hypertensive population from Palestine, and to determine the socio-demographic and clinical characteristics associated with poor HRQoL.Subject and methods
A cross sectional study was conducted, adopting the EuroQoL-5 Dimensions scale (EQ-5D-5 L) for the assessment of HRQoL. Hypertensive patients attending outpatients’ clinics at Al-Makhfyah primary health care clinic and from Alwatani Hospital, Nablus, Palestine were approached for study.Results
Four hundred and ten hypertensive patients were enrolled in the study. Of these, 213 patients (52 %) were female. The average age of the study population was 58.38?±?10.65 years. HRQoL was good, with a mean EQ-5D-5 L index value and EQ visual analogue scale (EQ-VAS) score of 0.80?±?0.16 and 74.1?±?15.6 respectively. There was a significant positive correlation (r?=?0.56; p?<?0.001) between the EQ-5D-5 L index values and the reported EQ-VAS scores. A significant difference in EQ-5D-5 L index values was found among participants when grouped according to age, occupation, marital status, income, educational level, duration of disease, total number of chronic diseases, and total number of medications (Kruskal–Wallis test; p-value?<?0.05), as well as gender and therapy type (Mann–Whitney test, p-value?<?0.05).Conclusions
This study highlighted that specific socio-demographic and disease-related characteristics of hypertensive patients as well as treatment factors were strongly associated with HRQoL. The study findings could be helpful in clinical practice, mainly in the early treatment of hypertensive patients, at a point where improving HRQoL is still possible. 相似文献10.
In this study the ureteric orifice position of duplex ureters in the bladder or urethra of children was correlated with the kidney configuration as determined by x-ray examination and in some by surgical excision and biopsy.A previous study1 of 51 necropsy speciments of duplex kidneys, ureters, and bladders of neonates, revealed a close correlation between ureteric oreteric orifice position and kidney morphology.This clinical study of children further confirms that the position and type of ureteral orifice act as guides to renal order and disorder in duplex kidneys. A radiographic classification of kidney configurrations was invoked to match and correlate form with orifice position. From this cystoradiographic study, it appears that renal abnormalities occur when ureteric buds arise from faulty locations in the Wolffian duct during embryogenesis. 相似文献
