Choi, J. H., Brummer, E., Kang, Y. J., Jones, P. P., Stevens, D. A. Oral itraconazole is attractive for continuing therapy in the patient who responds to initial iv therapy (CIII). He holds his degrees from Texas A&M University (Ph.D.) and Baylor University, and his current research . The laboratory has used molecular fingerprinting systems applied to the genomes of fungal species to develop tools to allow typing and differentiation of clinical isolates and for epidemiological and taxonomic purposes, particularly the epidemiology of Aspergillus and the Candida parapsilosis family. Steinbach, W. J., Stevens, D. A., Denning, D. W. Invasive aspergillosis in the setting of cardiac transplantation. Liked by David Stevens. Invasive aspergillosis is an important cause of morbidity and mortality in immunocompromised patients. In addition, the use of new drugs in the therapy of a parasitic infection, trypanosomiasis (Chagas disease), is being studied in vitro and in mice. What I See talks motherhood with Professor Alice Roberts. Dose-escalation of Abelcet alone did not increase reduction of cfu. View details for Web of Science ID 000175665800009. The efficacy of combination therapy for IA has not been established; sparse data on combination or sequential antifungal therapy depict interactions ranging from synergy to antagonism. In contrast, four of seven controls showed mild to severe meningitis, with arteritis detected in three animals. Because drugs with different mechanisms of action produced this effect, this suggests that it is the result of factors mediated by the cells. Contact Information Get David Stevens Contact Info. This had to take place to provide a safe and enjoyable environment for the patients and the staff. Cerebrospinal fluid (CSF) samples were obtained by cisternal puncture. Therapy should be prolonged beyond resolution of disease and reversible underlying predispositions (BIII). Born in . One hundred sixty patients were entered in two multicenter protocols to receive 400 to 2,000 mg of ketoconazole once daily for nonmeningeal or meningeal coccidiodomycosis. Because aspergillosis is an important pulmonary disease in birds, avian models have been used successfully to study preventative vaccines.

Best Match Powered by Whitepages Premium AGE -- David Stevens Little Neck, NY (Northeastern Queens) View Full Report Addresses 68th Ave, Little Neck, NY Phone Numbers (718) The main strength of these expeditions was the recording of architecture: the plans of the DOG, in particular, are detailed, and in attempting to record how human activity impacted upon buildings, they often bridge the gap between architectural and archaeological plans (Borchardt and Ricke, 1980). This easy-to-read presentation articulates how strategic thinking and group problem solving can be exploited on major infrastructure projects., Malcolm Pearson Draft Genome Sequence of the Human Pathogen Halomonas stevensii S18214(T). to add information, pictures and relationships, join in discussions and get credit for your contributions. Donald asks the courts to let him tweet. DiSalvo, H., Haiduven, D., Johnson, N., Reyes, V. V., Hench, C. P., Shaw, R., Stevens, D. A. Inhibitor kappa B and nuclear factor kappa B in granulocyte-macrophage colony-stimulating factor antagonism of dexamethasone suppression of the macrophage response to Aspergillus fumigatus conidia. Extraordinary results are gained in such a short period of time., Tony Roberts, Managing Director, South Pacific Corporate Limited, Dr Stevens has acted as a facilitator in a number of situations where the relationships between the various parties were difficult and complex. It describes a range of group problem solving methodologies and illustrates vividly how they can aid modern business. Genotype distribution differed among localities (p<0.0001); Mexico was unique (p<0.05) due to the high proportion of non-VII-1. View details for Web of Science ID 000268147700021, Disseminated coccidioidomycosis is a life-threatening infection. Monocytes inhibited hyphal growth. Combination therapy using available drugs is an attractive choice, yet primarily only anecdotal clinical data are available. [1], Stevens lived in Reading until his death on 7 April 1899. We think the most productive route to a fungal-specific vaccine may be a conjugate vaccine that combines the optimally configured glycan with a specific immunogenic protein. > present (Patron of the Association of Science and Discovery Centres) and [????] At day 10 PI, birds treated with VCZ at 20 mg/kg had significantly fewer fungi in the lungs as demonstrated by methenamine silver stain (P = 0.017) or immunohistochemistry, as compared to diluent-treated (P = 0.034). We also analysed gene expression with time in culture and found that while transposable elements and components of respiratory pathways tended to increase in expression with time, genes encoding ribosomal structural proteins and protein catabolism tended to sharply decrease in expression over time, particularly in yeast. View details for Web of Science ID 000075665900020. Among the Candida species causing bloodstream infections, Candida parapsilosis is one of the most frequently isolated. The therapy of coccidioidomycosis has been an early target, both experimentally and clinically, for study of new members of the azole class of drugs, because of the recognition that coccidioidomycosis is one of the most difficult mycoses to treat, and because our research group and our collaborators have been eager to pioneer new therapies for this problem pathogen. Plasma pharmacokinetic data were acquired from 30 patients receiving liposomal amphotericin B for empirical treatment of suspected invasive fungal infection. Cellular DNA, isolated after the lysis of protoplasts, was amplified by PCR using ITS1 and ITS4 primers, purified by liquid chromatography, and digested with restriction endonucleases. Her zodiac sign is Taurus. of Infectious Diseases and Geographic Medicine, Stanford University, Medical School: David A. Stevens, M.D. We assessed the role of MBL in experimental systemic aspergillosis. Killing of Bd by young peritoneal macrophages (PM) (46%) and adult PM (42%) was similar, and the enhancement of cells of both by IFN-gamma was similar. As a demonstration of the utility of the model to test antifungal activity, daily treatment with 10 or 50 mg/kg itraconazole significantly reduced dissemination to the liver and kidneys and reduced tongue CFU compared to controls. Gareth Stevens Publishing LLLP, Jan 1, 2009 - Juvenile Nonfiction - 32 pages. In summary, these data indicate that the risk factor for aspergillosis associated with DEX could be lessened in the pulmonary compartment with GM-CSF. Because vasculitis is seen frequently in patients with coccidioidal meningitis (CM), this study evaluated the presence of MMP-9 within the cerebrospinal fluid (CSF) of rabbits infected intracisternally with Coccidioides immitis arthroconidia. Sixty-two C. dubliniensis strains were collected from the authors of previously published studies. Tests for mannan antibodies and antigenaemia are currently of interest. The growing genus Halomonas includes bacteria favoring or tolerating high-saline/halide and high-pH environments. However, despite its beneficial effects, DEX puts patients at risk for opportunistic infections, especially pulmonary aspergillosis. At 50 mg/kg, itraconazole and fluconazole were equivalent, whereas itraconazole at 10 or 25 mg/kg prolonged survival compared to that achieved with fluconazole at these dosages (P < 0.05 and 0.01, respectively). Tell, L. A., Craigmill, A. L., Clemons, K. V., Sun, Y., Laizure, S. C., Clifford, A., Ina, J. H., Nugent-Deal, J. P., Woods, L., Stevens, D. A. Interaction between conidia, lung macrophages, immunosuppressants, proinflammatory cytokines and transcriptional regulation, The contribution of animal models of aspergillosis to understanding pathogenesis, therapy and virulence, Efficacy of caspofungin against central nervous system Aspergillus fumigatus infection in mice determined by TaqMan PCR and CFU methods. In addition, we will address the potential of immunotherapy in combination with conventional therapy.The data derived from animal model studies of antifungal drug efficacy have proven to be predictive of clinical utility. Both therapy dogs and visitation dogs require identification and certification of health and are excluded from certain areas of the facility, including intensive care units and isolation rooms. AMB and ITZ prolonged survival (P, <0.0001 to <0.05) compared with controls. A 16.5% salt concentration in brain-heart infusion broth, incubated at 35 degrees C for 48-72 hours, then subcultured to agar plates incubated in room air at 35 degrees C, proved optimal for selection and secondary isolation.

Work is still important to me, but I dont feel that it defines me in the way I certainly did before. The pharmacokinetics for both conventional and intermittent dosing were linear. Bronchoalveolar lavage is also very useful. For two of three patients, all three with two episodes of S. cerevisiae vaginitis, different strains were isolated during the recurrence of this disease. And we all need university research to be as relevant to wider society as possible". Sabino, R., Sampaio, P., Rosado, L., Stevens, D. A., Clemons, K. V., Pais, C. Itraconazole, a Commonly Used Antifungal that Inhibits Hedgehog Pathway Activity and Cancer Growth. The present era, which is characterized largely by the modifications of azole drugs, began with ketoconazole and brought agents which can be given orally and have increasing potency, decreasing toxicity and a broader spectrum of activity. Santa Clara Valley Medical Centre (SCVMC), a 600-bed county teaching hospital with specialized units (e.g., for burns, rehabilitation, and pediatric care), has implemented programs that incorporate animals into the healthcare setting. MDR1 overexpression was observed infrequently in some resistant isolates. Mannan binding lectin (MBL) deficiency has been associated with increased susceptibility to vaginitis in humans due to Candida albicans. These data suggest an endemic source of colonizing organisms, possibly from the hospital food preparation area. Mammalian estradiol influence on Paracoccidioides pathogenesis was investigated by focusing on the block of morphogenetic transformation, the role of the fungal estradiol-binding protein, and production of estrogenic ligands by the fungus. Ravuconazole at 25 mg/kg was superior in reduction of numbers of CFU in all tissues to controls or 25 mg of fluconazole per kg and to other regimens in at least three tissues. Creatinine levels were similar in the two regimens: the A : B ratio of the area under the curve for creatinine (AUC(CREATININE)) for days 2-7 was 1.09 (P=0.27) and for days 2-14 was 1.05 (P=0.51). Macrophages could be cultured in the presence or absence of serum during the initial 20 h adherence and establishment period, enabling study of the effect of serum factors. BAKER, G., FALK-WHYNES, J. and SIDOROVITCH, A., eds., Teaching for Integrative Learning: Innovations in University Practice. 0 people commented on this, Posted on July 18, 2014 Murine BAM killed Aspergillus fumigatus conidia by 33 +/- 4% (mean +/- SD) in a 2.5-h assay, unaffected by GM-CSF treatment. Additional studies are warranted. Isolates were recovered from multiple body sites of 23 patients (n = 180) from 1994 to 1995 and from 29 patients (n = 45) from 1997 to 2002; these plus 2 from the hospital kitchen were identified as S. cerevisiae. Headache, hair loss and anorexia were the most common symptoms experienced (each by 3% of patients), and eosinophilia and aspartate aminotransferase increases were the most common laboratory findings (12 and 10%, respectively). (Medical school lecturer of Anatomy), [????] The mortality of clinical Aspergillus infections necessitates consideration of the utility of a vaccine. We noted paradoxical turbid growth of Candida albicans isolates in broth in some high (supra-MIC) concentrations. Political Ideas in Practice: Problem-solving Political Theory. trivia, He has written a book which deserves to be read., Dr Stuart Green Recovery of CFU from the kidneys showed that dosages of CAS at 0.1 mg/kg and above were efficacious in the reduction of C. albicans, but were not curative. Fungicidal activity of peripheral blood polymorphonuclear neutrophils (PMN) from CD-1 (87%) was greater than that of BALB/c (75%) (P<0.05). What project can afford not to have the benefits of these secrets?, Many of Dr. Stevens facilitation secrets are revealed, but the extensive use of case studies for real organisations gives the reader tremendous insight in decision-making processes that lead to success for organisation, big or small., Filipo Sarti Factors associated with a poor prognosis have been defined and therapy is difficult because of the lack of a blood supply.

To compare two prominent methods, 29 isolates, typed by multilocus sequence typing (MLST), were typed by restriction fragment length polymorphism (RFLP). Interestingly, six of eight known vaginal isolates were group B, with four of those six being identical. The immune events that take place in the central nervous system (CNS) during cryptococcal infection are incompletely understood. Self - Gunsmith 1 . cytokines, chemokines, iNOS, matrix metalloproteinase-9 (MMP-9), that possibly contribute to vasculitis, temporal mRNA expression in brain basilar artery samples and MMP-9 protein in the CSF of male NZW rabbits infected intracisternally with 6.5 x 10(4) arthroconidia of Coccidioides immitis were assessed. Moreover, such treatment of PMN also enhanced the collaboration of PMN with VCZ. Little is known about the effects of serum factors or MBL on the interaction of Blastomyces dermatitidis, a pulmonary fungal pathogen, with macrophages or on tumor necrosis factor alpha (TNF-alpha) production. The central nervous system (CNS) is the most common site of dissemination during Aspergillus infection. We treated a patient who had acquired aspergillosis some 80 days after allogeneic bone marrow transplantation, with oral itraconazole, 600 mg daily. Albany. C. parapsilosis sensu stricto more frequently displayed (37%) paradoxical growth in CAS (P < or = 0.02). Caspofungin in RPMI 1640 exhibited dose-dependent inhibition, with concentrations of 0.1 and 0.05 microg/ml inhibiting 24.9% +/- 10.4% and 11.7% +/- 3.6%, respectively (n = 10; P < 0.01). No antifungal regimen effected cure. Some of his friends seem to think its a soft option but I dont think looking after kids can ever be described in those terms! Our work so far suggests that some proteins may be sufficiently cross-immunogenic, such that combined with the appropriate glycan, it may be possible to develop a pan-fungal vaccine. Alice Roberts and David Stevens have been married for 22 years. My daughter is now nearly four, and I also have a nine-month-old son. Pulmonary aspergillosis following bone marrow transplantation carries a mortality of 94%, irrespective of current treatment. ITZ-B suspension was prepared by dispersing the complex of the drug with hydroxypropyl-beta-cyclodextrin in water. In addition, YJM128 increased by 4-fold in the kidneys, whereas Y55 decreased by 16-fold. The mean histological scores for AmBi-treated rabbits were lower than those for FLC-treated and control rabbits (P < 0.016 and 0.0005, respectively); the scores for AMB-treated animals were lower than those for the controls (P < 0.0005) but were similar to those for FLC-treated rabbits. This paper describes two studies using mallard ducks (Anas platyrhynchos). Ravuconazole (RCZ) was evaluated for efficacy in comparison to fluconazole (FCZ) and itraconazole (ITZ) in murine models of disseminated histoplasmosis. of California, Davis). Cytokine production by HKY-stimulated cells from PBS-vaccinated mice was lower than those from HKY-vaccinated (P<0.05). It is believed to be correct at the time of inputting and is presented here in good faith. The anthropologist David Graeber . Clinical assessments were done daily; cerebrospinal fluid and blood samples were obtained on day 15 and upon euthanasia. These results suggest that VCZ would have good efficacy in the treatment of Cn infection in humans. Statistical analysis of the data demonstrates a strong correlation between homozygosity at the MTL locus and azole resistance (P<0 small middle dot003). In one patient, fungemia was accompanied by clinical and laboratory evidence of Broviac catheter infection. stone slab (or stela) that furnished the first historical evidence of King David from the Bible..

Ravuconazole has good efficacy and the potential to cure mucosal candidosis in the absence of a functional immune response. Overexpression of FLU1, an efflux pump gene related to MDR1, did not correlate with resistance, nor did overexpression of ERG11. Choi, J., Kwon, E., Park, C., Choi, S., Lee, D., Yoo, J., Shin, W., Stevens, D. A. IL-6 production in vivo in response to fungal-serum complexes could affect pathogenesis by opposing the host defense modulation by proinflammatory cytokines or by modulating the destructive effects of inflammation on host tissues. View details for Web of Science ID 000167613000005 A systemic model of candidiasis was studied in CD-1 mice by intravenous inoculation of different isolates of C. albicans.

The activity of the echinocandin caspofungin (MK-0991), a 1,3-beta-D-glucan synthase inhibitor, against Aspergillus fumigatus with and without human sera was studied. At 0.01 and 0.05 microg ml(-1) of VCZ, G-CSF or GM-CSF enhanced PMN killing to 92% and 93% or 87% and 94%, respectively. Clemons, J.H. Our results show susceptibility to vaginal candidiasis is independent of the major histocompatibility locus H2 haplotype and any effect ascribable to use of particular commercial mouse suppliers. The site facilitates research and collaboration in academic endeavors. Overall, there remains no optimal, single method for determination of fungal load of Aspergillus and it may be that a combination of methods (e.g., CFU and qPCR) should be used.

Login These data show that GM-CSF in vivo blocks the in vivo immunosuppressive effects of DEX on BAM killing of conidia and suggest a potential use of GM-CSF in patients at risk for aspergillosis due to immunosuppressive DEX treatment. A patient developed Halomonas johnsoniae (previously reported only as dialysis unit environmental contaminants) bacteremia. This emphasizes the potential importance of a positive culture for Aspergillus in the critically ill, the need for awareness about possible aspergillosis in patients lacking the classical risk factors, and readiness to proceed with appropriate diagnostic maneuvers. In a second, open-label part of the trial, all the patients received 200 mg of itraconazole per day for 16 weeks.There were responses in 13 of 28 patients in the itraconazole group (46 percent), as compared with 5 of 27 patients in the placebo group (19 percent, P=0.04). 2011 Kassabaum, Megan C.; David J. Cranford and Erin Stevens Nelson. Candida albicans given in the drinking water resulted in oral infection by day 3 that significantly increased from days 10 to 15 and mucosal infection with 4 to 7 log(10) Candida CFU in the esophagus, stomach, small intestine, and cecum. Five patients received therapy for >or= 12 months. Although no well-designed studies have been carried out, the available data support the use of corticosteroids for acute exacerbations of ABPA (AII).
