As HLA testing is becoming a major vehicle for parentage determination with non-excluded, alleged fathers being compared to their racial peers, it is important to ensure that the population data used accurately reflect the genetic profile of the region from which the alleged fathers are drawn. This paper presents data on the HLA profile of Black and White residents of North Carolina. Significant differences were observed for certain antigens when the North Carolina data were compared to nationally derived population tables. Differences were observed for B7 (increase) and Bw16 (decrease) in Whites and A10 (decrease), B7 (increase) and Bw42 (decrease) in Blacks. Internal controls comparing the testing from the two participating centers showed complete agreement for White persons, but a significant difference for B5 between the two Black populations. 相似文献

Bronchial inhalation challenge with ultrasonically nebulized saline; comparison to exercise-induced asthma 总被引:2,自引:0,他引:2
The airway response to ultrasonically nebulized sodium chloride of increasing concentration (0.9%, 2.5%, 5%, 10%, and 20%) was assessed in twenty asthmatic patients and five healthy subjects. Their response was compared to a standard exercise provocation test. Each concentration was inhaled for five minutes and the airway response was assessed by the measurement of the maximal expiratory flow volume curves. While only 65% of the patients developed significant bronchoconstriction to exercise, 90% had such response to inhaled sodium chloride of 20% or less. None of the healthy subjects showed any significant airway response. It is concluded that the inhalation of hypertonic sodium chloride is a sensitive method for the evaluation of airway hyperreactivity and can be used instead of the exercise provocation test in asthmatic patients. 相似文献

Introduction : In Peru, transgender women (TW) experience unique vulnerabilities for HIV infection due to factors that limit access to, and quality of, HIV prevention, treatment and care services. Yet, despite recent advances in understanding factors associated with HIV vulnerability among TW globally, limited scholarship has examined how Peruvian TW cope with this reality and how existing community‐level resilience strategies are enacted despite pervasive social and economic exclusion facing the community. Addressing this need, our study applies the understanding of social capital as a social determinant of health and examines its relationship to HIV vulnerabilities to TW in Peru. Methods : Using qualitative methodology to provide an in‐depth portrait, we assessed (1) intersections between social marginalization, social capital and HIV vulnerabilities; and (2) community‐level resilience strategies employed by TW to buffer against social marginalization and to link to needed HIV‐related services in Peru. Between January and February 2015, 48 TW participated (mean age = 29, range = 18–44) in this study that included focus group discussions and demographic surveys. Analyses were guided by an immersion crystallization approach and all coding was conducted using Dedoose Version 6.1.18. Results : Themes associated with HIV vulnerability included experiences of multilevel stigma and limited occupational opportunities that placed TW at risk for, and limited their engagement with, existing HIV services. Emergent resiliency‐based strategies included peer‐to‐peer and intergenerational knowledge sharing, supportive clinical services (e.g. group‐based clinic attendance) and emotional support through social cohesion (i.e. feeling part of a community). Conclusion : This study highlights the importance of TW communities as support structures that create and deploy social resiliency‐based strategies aimed at deterring and mitigating the impact of social vulnerabilities to discrimination, marginalization and HIV risk for individual TW in Peru. Public health strategies seeking to provide HIV prevention, treatment and care for this population will benefit from recognizing existing social capital within TW communities and incorporating its strengths within HIV prevention interventions. At the intersection of HIV vulnerabilities and collective agency, dimensions of bridging and bonding social capital emerged as resiliency strategies used by TW to access needed healthcare services in Peru. Fostering TW solidarity and peer support are key components to ensure acceptability and sustainability of HIV prevention and promotion efforts. 相似文献

The first successful demonstration that effective T cell depletion can enable immune reconstitution without causing graft vs. host disease (GVHD) in SCID patients was achieved in 1980 using lectin-separated haploidentical hematopoietic stem cells. Recipients exhibited immune tolerance towards donor antigens with a follow-up of more than 2 decades. In leukemia patients undergoing supralethal radio- and chemotherapy, T cell-depleted transplants are vigorously rejected by residual host T cells; this barrier was first overcome in 1993 by the use of megadose stem cell transplants. This clinical observation can be explained, in part, by the demonstration that cells within the CD34 compartment, as well as their immediate early myeloid progeny, are endowed with veto activity. Engraftment of mismatched hematopoietic stem cells following reduced intensity conditioning, still represents a major challenge. Progress made recently in murine studies by different approaches including the use of new co-stimulatory blockade agents, as well as by tolerance inducing cells such as anti-3rd party veto CTLs, NK T cells, and T regulatory cells, suggests several promising modalities for clinical translation. 相似文献

OBJECTIVE: To establish an efficient and sensitive technique for recovering vancomycin-resistant enterococci (VRE) from perianal and environmental samples collected during implementation of control measures for an outbreak of VRE. DESIGN: Perianal and environmental samples were collected in triplicate on sterile swabs. One swab was used to inoculate a selective broth medium containing 6 pg of vancomycin and 8 pg of ciprofloxacin per mL, one to inoculate Campylobacter agar containing 10 microg/mL of vancomycin, and one to inoculate Enterococcosel agar containing 8 microg/mL of vancomycin. SETTING: Samples were collected in the intensive care units of a 600-bed university hospital over a period of 2 months. SAMPLE SELECTION: Patients and their immediate environment were sampled if they resided in a ward with a patient known to be colonized or infected with VRE. RESULTS: Of the 88 perianal samples obtained from 63 patients, 37 were positive for VRE by broth culture, with 36 also recovered on both types of solid media (sensitivity, 97.3%; negative predictive value, 98.1%). Of the initial samples collected from each of the 63 patients, 20 were positive for VRE by all methods. Of the 500 environmental samples cultured, 139 were positive for VRE in broth, with only 33 recovered on Campylobacter agar (sensitivity, 23.7%; negative predictive value, 77.2%) and 22 on Enterococcosel agar (sensitivity, 15.8%; negative predictive value, 75.2%). CONCLUSIONS: Our data indicate that, when performing surveillance cultures during an outbreak of VRE, use of an enrichment broth medium is required to recover VRE contaminating environmental surfaces; however, direct inoculation to selective solid medium is adequate to recover VRE in patient perianal specimens. 相似文献

Since 2006, the Centers for Disease Control and Prevention (CDC) has recommended routine, voluntary HIV testing for persons aged 13-64 in all health care settings, including the elimination of separate informed consent, which remains in effect in five states including Massachusetts. Community health centers (CHCs) represent an important HIV testing site for at-risk populations. From April to December 2008 a qualitative interview was administered to one senior personnel from each of 30 CHCs in Massachusetts, to identify barriers and facilitators to implementing CDC recommendations and to elucidate strategies to improve routine HIV testing. The following themes emerged as routine HIV testing barriers: (1) provider time constraints, including time to administer counseling and separate informed consent; (2) lack of funding, staff, and space; (3) provider, patient, and community discomfort; (4) inconsistent levels of awareness regarding CDC recommendations; and (5) perceived incompatibility with Massachusetts HIV testing policy. Facilitators included designation of personnel to serve as organizational "champions" for routine testing and use of clinical reminders within electronic medical records to prompt HIV testing. Strategies identified to improve routine HIV testing rates among Massachusetts CHCs included more explicit state-level guidelines; organizational buy-in; collaborative analysis to integrate testing within existing activities; and provider, patient and community education. 相似文献

BACKGROUND: The purpose of this project was to determine the prevalence of asymptomatic sexually transmitted diseases (STDs) among men who have sex with men (MSM) in the Boston area who had been sexually active (oral and/or anal sex) with another male within the past year. METHODS: Over a 1-month period (March 2007), asymptomatic MSM in care at a Boston community health center (n = 114) were screened for gonorrhea and chlamydia using the BD ProbeTec technique. Deidentified medical record data were analyzed and linked to prevalence monitoring results. RESULTS: Eleven percent of the sample tested positive for one of the 2 STDs (gonorrhea or chlamydia) from at least one mucosal site. Individuals who were infected with an STD were considerably more likely to have a prior history of one or more STD infections when compared with those without an STD history (OR = 3.69; P <0.02). There were no significant differences observed in psychosocial and other behavioral risk factors between patients with or without an STD. CONCLUSIONS: Screening asymptomatic MSM using nucleic acid amplification tests (NAATs) revealed a substantial STD burden that might not have been diagnosed using traditional assays. These data are critical for the design of effective public health interventions for this population. 相似文献
