This article estimates the population prevalence of current injection drug users (IDUs) in 96 large US metropolitan areas
to facilitate structural analyses of its predictors and sequelae and assesses the extent to which drug abuse treatment and
human immunodeficiency virus (HIV) counseling and testing are made available to drug injectors in each metropolitan area.
We estimated the total number of current IDUs in the United States and then allocated the large metropolitan area total among
large metropolitan areas using four different multiplier methods. Mean values were used as best estimates, and their validity
and limitations were assessed. Prevalence of drug injectors per 10,000 population varied from 19 to 173 (median 60; interquartile
range 42–87). Proportions of drug injectors in treatment varied from 1.0% to 39.3% (median 8.6%); and the ratio of HIV counseling
and testing events to the estimated number of IDUs varied from 0.013 to 0.285 (median 0.082). Despite limitations in the accuracy
of these estimates, they can be used for structural analyses of the correlates and predictors of the population density of
drug injectors in metropolitan areas and for assessing the extent of service delivery to drug injectors. Although service
provision levels varied considerably, few if any metropolitan areas seemed to be providing adequate levels of services. 相似文献

PURPOSE: Pharmacist involvement in antimicrobial use at small rural hospitals in four Western states was studied. METHODS: Surveys were mailed in July 2000 to hospitals with a daily patient census of <150 in Idaho, Nevada, Utah, and eastern Washington. RESULTS: Seventy-seven (77%) of 100 hospitals returned completed surveys. Only 5% of the hospitals had onsite pharmacists 24 hours per day. An onsite pharmacist was present for a median of 26 hours per week in hospitals without 24-hour pharmacist coverage (range, 0-116 hr/wk). Many hospitals (71%) had policies for monitoring or controlling antimicrobial use, but only 28% had a system capable of monitoring compliance with such policies. Few hospitals had systems for recommending changes in antimicrobial selection on the basis of susceptibility test results (27%) or for monitoring physician compliance with dosage recommendations by pharmacists (21%). Onsite pharmacist hours were significantly associated with pharmacists being involved in the initial ordering of antibiotics and providing active oversight of antimicrobial use. There was a negative correlation between onsite pharmacist hours and use of third-generation cephalosporins and carbapenems. CONCLUSION: A survey showed that rural hospital pharmacists in four Western states spent relatively little time monitoring and influencing antimicrobial prescribing. 相似文献

Recent studies in mouse models of cancer have shown that exercise improves tumor vascular function, thereby improving chemotherapy delivery and efficacy. However, the mechanisms underlying this improvement remain unclear and the effect of exercise on Ewing sarcoma (ES), a pediatric bone and soft tissue cancer, is unknown. The effect of exercise on tumor vascular hyperpermeability, which inversely correlates with drug delivery to the tumor, has also not been evaluated. We hypothesized that exercise improves chemotherapy efficacy by enhancing its delivery through improving tumor vascular permeability. We treated ES‐bearing mice with doxorubicin with or without moderate treadmill exercise. Exercise did not significantly alter ES tumor vessel morphology. However, compared to control mice, tumors of exercised mice had significantly reduced hyperpermeability, significantly decreased hypoxia, and higher doxorubicin penetration. Compared to doxorubicin alone, doxorubicin plus exercise inhibited tumor growth more efficiently. We evaluated endothelial cell sphingosine‐1‐phosphate receptors 1 and 2 (S1PR1 and S1PR2) as potential mediators of the improved vascular permeability and increased function afforded by exercise. Relative to tumors from control mice, vessels in tumors from exercised mice had increased S1PR1 and decreased S1PR2 expression. Our results support a model in which exercise remodels ES vasculature to reduce vessel hyperpermeability, potentially via modulation of S1PR1 and S1PR2, thereby improving doxorubicin delivery and inhibiting tumor growth more than doxorubicin alone does. Our data suggest moderate aerobic exercise should be tested in clinical trials as a potentially useful adjuvant to standard chemotherapy for patients with ES. 相似文献

Cytomegalovirus (CMV) infection in solid-organ transplantation is associated with increased morbidity and mortality, particularly if a CMV mutant strain with antiviral resistance emerges. Monitoring CMV–specific T cell response could provide relevant information for patient care. We and others have shown the involvement of Vδ2neg
γδ T cells in controlling CMV infection. Here, we assessed if Vδ2neg
γδ T cell kinetics in peripheral blood predict CMV infection resolution and emergence of a mutant strain in high–risk recipients of kidney transplants, including 168 seronegative recipients receiving organs from seropositive donors (D+R−) and 104 seropositive recipients receiving antithymocyte globulins (R+/ATG). Vδ2neg
γδ T cell percentages were serially determined in patients grafted between 2003 and 2011. The growing phase of Vδ2neg
γδ T cells was monitored in each infected patient, and the expansion rate during this phase was estimated individually by a linear mixed model. A Vδ2neg
γδ T cell expansion rate of ˃0.06% per day predicted the growing phase. The time after infection at which an expansion rate of 0.06% per day occurred was correlated with the resolution of CMV DNAemia (r=0.91; P<0.001). At 49 days of antiviral treatment, Vδ2neg
γδ T cell expansion onset was associated with recovery, whereas absence of expansion was associated with recurrent disease and DNAemia. The appearance of antiviral–resistant mutant CMV strains was associated with delayed Vδ2neg
γδ T cell expansion (P<0.001). In conclusion, longitudinal surveillance of Vδ2neg
γδ T cells in recipients of kidney transplants may predict CMV infection resolution and antiviral drug resistance. 相似文献

Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare benign tumor of uncertain etiology, arising in the craniospinal axis. CAPNON typically arises in isolation, with only two prior reports of a concurrent second neoplasm. Here, we report the case of a male 17‐year‐old who presented with new‐onset seizures. MRIs revealed a 2 cm extra‐axial solid‐cystic mass, arising at the left temporo‐occipital junction and abutting the dura with marked surrounding parenchymal vasogenic edema. The solid components demonstrated dense calcification and avid enhancement. Gross total surgical resection was performed. Histopathological examination revealed central regions showing characteristic features of CAPNON. Toward the periphery, the CAPNON was intimately associated with and sharply demarcated from a meningioma, which showed up to five mitoses per 10 high‐power fields and had invasion into the adjacent brain parenchyma, warranting a WHO grade II designation. This is the first report of CAPNON arising in association with a meningioma. The coexistence of these two tumors raises the possibility of a reactive/dysplastic etiology for CAPNON. 相似文献

One-hundred and seventy head chefs from the Republic of Ireland scored 59 variables for success on two scales: (a) competencies needed for success (NS), and (b) personal ownership of these competencies (PO). Results showed that variables were rated with means of 1.18 (extremely important) to 3.23 (moderately important). The top three were an ability to work hard, commitment to quality, and knowledge of Hazard Analysis and Critical Control Points (HACCP). Variables rated lower in ownership than importance highlight areas for culinary educators to develop training programs. Average wages of head chefs (objective success) mirror the average industrial wage, but higher wages were gained with longer time working. Eighty percent of head chefs were satisfied (subjective success) in their current jobs. Factor analysis showed the factors needed to succeed in the culinary industry include professionalism, individual characteristics, leadership skills, management skills, and interaction with the job context. Applications for industry include talent management, mentoring future leaders, reducing staff turnover, and curriculum development. 相似文献

A cross-sectional study was undertaken in Nakuru, Kenya to assess the prevalence of refractive error and the spectacle coverage in a population aged ≥50 years. Of the 5,010 subjects who were eligible, 4,414 underwent examination (response rate 88.1 %). LogMAR visual acuity was assessed in all participants and refractive error was measured in both eyes using a Topcon auto refractor RM8800. Detailed interviews were undertaken and ownership of spectacles was assessed. Refractive error was responsible for 51.7 % of overall visual impairment (VI), 85.3 % (n = 191) of subjects with mild VI, 42.7 % (n = 152) of subjects with moderate VI, 16.7 % (n = 3) of subjects with severe VI and no cases of blindness. Myopia was more common than hyperopia affecting 59.5 % of those with refractive error compared to 27.4 % for hyperopia. High myopia (<?5.0 DS) was also more common than extreme hyperopia (>+5.0 DS). Of those who needed distance spectacles (spectacle coverage), 25.5 % owned spectacles. In conclusion, the oldest, most poor and least educated are most likely to have no spectacles and they should be specifically targeted when refractive services are put in place. 相似文献

This paper examines the religious law and customs regarding sexual conduct among the orthodox Jewish community. There is a vast and complex set of rules governing all sexual and matrimonial behaviour, which is closely observed by the Hassidic movement and other sectors of orthodox Judaism. As therapists and counsellors it is essential to have a grasp of these laws before attempting to counsel such couples. The information was collected from interviews with members of the Manchester Jewish community and a review of religious texts which are used for the instruction of newlyweds. 相似文献

Pattern hair loss (PHL) is the most common form of baldness in both sexes. The Norwood–Hamilton classification is the most commonly used classification worldwide, but it has many limitations. The basic and specific (BASP) classification was introduced as an improvement over the Norwood–Hamilton classification. Previous research was done to estimate the reliability of the Norwood–Hamilton classification and the result was unsatisfactory. However, the reliability of the BASP and Norwood–Hamilton classifications has not yet been compared. Eight dermatological specialists, 17 dermatological residents and 15 general physicians classified PHL in 100 sets of photographs using both the BASP and Norwood–Hamilton classifications. Intergroup reproducibility was evaluated by examining the match rate of the individual data in each group and the match rate between hair specialist and the other examiners. Intragroup repeatability was determined by calculating the match rate between the first and second studies. In terms of intergroup reproducibility of the match rate for individual data in each group, the basic type had the best agreement, the specific type had the second best, and the Norwood–Hamilton classification had the lowest match rate. In comparison, hair specialist and intragroup repeatability showed the same patterns. The BASP classification not only distinguishes all kinds of hair loss patterns, but also has better reproducibility and repeatability than the Norwood–Hamilton classification. 相似文献
