We have shown that dermatophyte species can be easily identified on the basis of a DNA sequence encoding a part of the large-subunit (LSU) rRNA (28S rRNA) by using the MicroSeq D2 LSU rRNA Fungal Sequencing Kit. Two taxa causing distinct dermatophytoses were clearly distinguished among isolates of the Trichophyton mentagrophytes species complex. 相似文献

In the United States, International Classification of Disease Clinical Modification (ICD-9-CM, the ninth revision) diagnosis codes are commonly used to identify patient cohorts and to conduct financial analyses related to disease. In October 2015, the healthcare system of the United States will transition to ICD-10-CM (the tenth revision) diagnosis codes. One challenge posed to clinical researchers and other analysts is conducting diagnosis-related queries across datasets containing both coding schemes. Further, healthcare administrators will manage growth, trends, and strategic planning with these dually-coded datasets. The majority of the ICD-9-CM to ICD-10-CM translations are complex and nonreciprocal, creating convoluted representations and meanings. Similarly, mapping back from ICD-10-CM to ICD-9-CM is equally complex, yet different from mapping forward, as relationships are likewise nonreciprocal. Indeed, 10 of the 21 top clinical categories are complex as 78% of their diagnosis codes are labeled as “convoluted” by our analyses. Analysis and research related to external causes of morbidity, injury, and poisoning will face the greatest challenges due to 41 745 (90%) convolutions and a decrease in the number of codes. We created a web portal tool and translation tables to list all ICD-9-CM diagnosis codes related to the specific input of ICD-10-CM diagnosis codes and their level of complexity: “identity” (reciprocal), “class-to-subclass,” “subclass-to-class,” “convoluted,” or “no mapping.” These tools provide guidance on ambiguous and complex translations to reveal where reports or analyses may be challenging to impossible.Web portal: http://www.lussierlab.org/transition-to-ICD9CM/Tables annotated with levels of translation complexity: http://www.lussierlab.org/publications/ICD10to9 相似文献

Erythropoietin prevents hypoxia/ischemia-induced DNA fragmentation in an experimental model of perinatal asphyxia 总被引:8,自引:0,他引:8

Erythropoietin (EPO) prevents neuronal damage following ischemic, metabolic and excitotoxic stress. Recent studies have shown that EPO plays a significant role in the developing brain. The present study investigates the effect of EPO administration on hypoxic-ischemic brain injury and the possibility that its neuroprotective action may be associated with anti-apoptotic activity. Seven-day-old rats were treated with EPO (2000 U/kg) and subjected to a modified Levine procedure. EPO administration before the hypoxic-ischemic insult significantly reduces the severity of brain damage and improved the short-term functional brain recovery. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling and DNA electrophoresis displayed no evidence of DNA fragmentation in EPO-treated animals. These results suggest that EPO might protect the neonatal rat brain by anti-apoptotic mechanisms. 相似文献

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using autografts or allografts is being performed with
increasing frequency, particularly in young athletes. Although the procedure is generally well tolerated, with good success
rates, early and late complications have been documented. As clinical manifestations of graft complications are often non-specific
and plain radiographs cannot directly visualize the graft and the adjacent soft tissues, MR imaging has a definite role in
the diagnosis of complications after ACL reconstruction and may direct subsequent therapeutic management. Our purpose is to
review the normal MR imaging of the ACL graft and present the MR imaging findings of a wide spectrum of complications after
ACL reconstruction, such as graft impingement, graft rupture, cystic degeneration of the graft, postoperative infection of
the knee, diffuse and localized (i.e., cyclops lesion) arthrofibrosis, and associated donor site abnormalities. Awareness
of the MR imaging findings of complications as well as the normal appearances of the normal ACL graft is essential for correct
interpretation.

Obesity as a potential risk factor for adenocarcinomas and squamous cell carcinomas of the uterine cervix 总被引:2,自引:0,他引:2
Lacey JV Swanson CA Brinton LA Altekruse SF Barnes WA Gravitt PE Greenberg MD Hadjimichael OC McGowan L Mortel R Schwartz PE Kurman RJ Hildesheim A 《Cancer》2003,98(4):814-821
BACKGROUND: Hormonal factors may play a more prominent role in cervical adenocarcinoma than squamous cell carcinoma. The authors evaluated whether obesity, which can influence hormone levels, was associated with adenocarcinoma and squamous cell carcinoma. METHODS: This case-control study included 124 patients with adenocarcinoma, 139 matched patients with squamous cell carcinoma, and 307 matched community control participants. All participants completed interviews and provided cervicovaginal samples for human papillomavirus (HPV) testing. Polytomous logistic regression-generated odds ratios (ORs) and 95% confidence intervals (95% CIs) for self-reported height and weight, body mass index (BMI; kg/m(2)), and measured waist-to-hip ratio (WHR) for both histologic types were adjusted and stratified for HPV and other confounders. RESULTS: Height, weight, BMI, and WHR were positively associated with adenocarcinoma. BMI >or= 30 kg/m(2) (vs. BMI < 25 kg/m(2); OR, 2.1 and 95% CI, 1.1-3.8) and WHR in the highest tertile (vs. the lowest tertile; OR, 1.8 and 95% CI, 0.97-3.3) were associated with adenocarcinoma. Neither height nor weight was found to be associated with squamous cell carcinoma, and associations for BMI >or= 30 kg/m(2) (OR, 1.6) and WHR in the highest tertile (OR, 1.6) were weaker and were not statistically significant. Analyses using only HPV positive controls showed similar associations. The data were adjusted for and stratified by screening, but higher BMI and WHR were associated with higher disease stage at diagnosis, even among recently and frequently screened patients with adenocarcinoma. Thus, residual confounding by screening could not be excluded as an explanation for the associations. CONCLUSIONS: Obesity and body fat distribution were associated more strongly with adenocarcinoma than with squamous cell carcinoma. Although questions about screening remain, obesity may have a particular influence on the risk of glandular cervical carcinoma. 相似文献

Associations between smoking and adenocarcinomas and squamous cell carcinomas of the uterine cervix (United States) 总被引:3,自引:0,他引:3
Lacey JV Frisch M Brinton LA Abbas FM Barnes WA Gravitt PE Greenberg MD Greene SM Hadjimichael OC McGowan L Mortel R Schwartz PE Zaino RJ Hildesheim A 《Cancer causes & control : CCC》2001,12(2):153-161
Objectives: Few studies of smoking and cervical carcinoma have addressed the rare cervical adenocarcinomas or used DNA-based tests to control for human papillomavirus (HPV) infection.
Methods: This multicenter case–control study included 124 adenocarcinoma cases, 307 community controls (matched on age, race, and residence to adenocarcinoma cases), and 139 squamous carcinoma cases (matched on age, diagnosis date, clinic, and disease stage to adenocarcinoma cases). Participants completed risk-factor interviews and volunteered cervical samples for PCR-based HPV testing. Polychotomous logistic regression generated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for both histologic types.
Results: Eighteen percent of adenocarcinoma cases, 43% of squamous carcinoma cases, and 22% of controls were current smokers. After control for HPV and other questionnaire data, adenocarcinomas were consistently inversely associated with smoking (e.g. current: OR = 0.6, 95% CI 0.3–1.1; 1 pack per day: OR = 0.7, 95% CI 0.4–1.3), while squamous carcinomas were positively associated with smoking (e.g. current: OR = 1.6, 95% CI 0.9–2.9; 1 pack per day: OR = 1.8, 95% CI 1.0–3.3). Results in analyses restricted to HPV-positive controls were similar.
Conclusion: Smoking has opposite associations with cervical adenocarcinomas and squamous carcinomas. Although both histologic types are caused by HPV and arise in the cervix, etiologic co-factors for these tumors may differ. 相似文献

Disability and treatment patterns of multiple sclerosis patients in United States: a comparison of veterans and nonveterans 总被引:3,自引:0,他引:3

The Veterans Health Administration (VHA) is the largest integrated healthcare system in the world and provides care to approximately 20,000 multiple sclerosis (MS) patients. Here, we report that these MS patients are disproportionately more likely to be older, male, unemployed, and disabled with lower levels of education and financial resources when compared to veterans not receiving care within the VHA or to nonveteran MS patients. When comparing the VHA MS patients to a cohort of nonveteran MS patients matched for age, sex, and disability, we found that veterans receiving care within the VHA were equally likely to have received care from a neurologist and more likely to have received care from rehabilitation specialists and primary care physicians than nonveterans. Similarly, veterans in the VHA were more likely to receive therapy with certain symptomatic medications but were less likely to be treated with disease-modifying agents for MS (DMAMS) than nonveterans. When treated with DMAMS, they are more likely to be treated with Avonex and significantly less likely to receive treatment with Copaxone or Novantrone. 相似文献
