Eastern Europe and Central Asia represent one of the few regions globally where there is a continued increase in the incidence of HIV infection. For example, in Eastern Europe the rate of diagnosed cases of HIV infection per 100 000 population has increased from 11.7 in 2004 to 22.5 in 2011. Initially propelled by injection drug use, heterosexual transmission has now become a major driver of new infections in the region. Nonetheless substance use remains an important factor, with its control limited by challenges in scaling up harm reduction efforts. While most countries have implemented opioid substitution therapy programs, their scale remains very limited. Similarly, coverage of needles syringe programs across the region is variable. Complicating the control of HIV has been the emergence of non-injection drugs and inadequate access to antiretroviral therapy. In addition, structural barriers and stigma toward HIV infected people may contribute to the high proportion of late presentations for HIV care. Finally in the wake of the HIV epidemic, high rates of hepatitis C infection and tuberculosis have been noted. 相似文献

Simultaneous cultivations in anaerobiosis, aerobiosis and with microaerobic gas mixture were used to clarify the bile (oxgall) effects on the pure and mixed cultures of enterobacterial strains in simulations in Portable Microbe Enrichment Unit (PMEU) linked with ChemPro100i® gas detector. The effects of vancomycin were evaluated in aerobic cultures. Growth and metabolic activity of cultures were also followed by measuring sugar consumption, pH alterations, and colony counts on BD CHROMagar? Orientation plates. Results showed that the two fermentatively different strains of facultative anaerobes, Escherichia coli E 17 and Klebsiella mobilis ATCC 13048 grew in balance regardless of oxygen level, bile acid concentration or other components of the mixed cultures, Bacillus cereus or Staphylococcus aureus. When the evaporations of the mixed cultures of E. coli, K. mobilis and S. aureus were compared with the emissions of the corresponding pure cultures by ChemPro100i® gas sensing detector, the pure cultures of bile resistant E. coli and K. mobilis produced more gaseous components than the mixed culture indicating that these organisms cooperate and use the substrate more effectively together than separately. A survey of the aseptic bacterial isolations from the bile tract in a big University Hospital, (Salzburg, Austria) during 3 years, showed that these bacterial groups dominated. Only 13.24% of the 287 patient samples were sterile, and around 180 strains of both E. coli and Klebsiella/Enterobacter groups were found amongst 973 isolates from 249 patients (together 35.57%). Enterococcus sp. accounted for 246 isolates being the largest group of strains (24.25% of all the isolates). In anaerobiosis it was shown that Klebsiella neutralized the acids produced in the mixed acid fermentation of the E. coli. The ethanol produced from both groups evaporated in the gas stream of the PMEU culturing step and its formation also removes excess acidity from the cultures. The synergistic behaviour and symbiotic function between E. coli and Klebsiella/Enterobacter strains is suggested. 相似文献

PURPOSE: The study describes nurses' occupational stress and implementation of information technology on acute psychiatric wards. DESIGN AND METHODS: The sample consisted of 146 Finnish nurses. The data were collected using a structured questionnaire in 2006. FINDINGS: Eleven percent of the nurses felt that work was very mentally strenuous and 45% felt that it was rather mentally strenuous. Male nurses reported more stress and dissatisfaction than female nurses. Nurses with very positive attitudes towards Internet use reported less stress and more job satisfaction than nurses with neutral attitudes towards Internet use. PRACTICE IMPLICATIONS: By supporting positive attitudes to information technology in nurses' daily work, we may increase their job satisfaction and thereby reduce their stress experiences. 相似文献

We describe a case of linear porokeratosis with associated bone resorption in a 17‐year‐old female with marked improvement after 2% cholesterol/2% lovastatin ointment application. Porokeratosis is a heterogenous group of keratinization disorders characterized by a cornoid lamella, consisting of focal dyskeratotic cells in the granular layer and columns of parakeratosis. The pathogenesis of porokeratosis is not fully elucidated; however, germline mutations have recently been identified in the mevalonate pathway which can lead to a buildup of metabolites that could play a role in dysmaturation. There has only been one prior report of an affected distal digit with underlying bone resorption in association with linear porokeratosis. 相似文献

Background: It is often difficult to establish clinical relevance of metal exposure in cobalt‐allergic patients. Dermatologists and patients may incorrectly assume that many metallic items release cobalt at levels that may cause cobalt dermatitis. Cobalt‐allergic patients may be unaware that they are exposed to cobalt from handling work items, causing hand dermatitis. Objectives: To present early findings with a newly developed cobalt spot test. Methods and Results: A cobalt spot test based on disodium‐1‐nitroso‐2‐naphthol‐3,6‐disulfonate was able to identify cobalt release at 8.3 ppm. The test may also be used as a gel test if combined with an agar preparation. We found no false‐positive reactions when testing metals and alloys known not to contain cobalt. However, one cobalt‐containing alloy, which elicited cobalt dermatitis in cobalt‐allergic patients, was negative upon cobalt gel testing. Conclusions: The cobalt test detects amounts of cobalt release that approximate the elicitation concentration seen in cobalt‐allergic patients. It may serve as a useful tool in dermatology offices and workplaces. 相似文献

Objective. We sought to determine the antiinflammatory properties of lymecycline in the long-term treatment of reactive arthritis (ReA). Methods. Quantitative assay of collagenase activity by densitometry after sodium dodecyl sulfatepolyacrylamide gel electrophoresis. Results. Therapeutic levels of lymecycline do not directly inhibit the activity of human neutrophil interstitial collagenase, but can prevent the oxidative activation of latent human neutrophil collagenase. Conclusion. This non-antimicrobial, anticollagenolytic property of lymecycline may contribute to its therapeutic efficacy in the treatment of patients with ReA. 相似文献
