Staphylococcus epidermidis is one of the most important coagulase-negative staphylococci (CoNS) in the NICU. Various bacterial virulence factors of this opportunistic microorganism such as intercellular protein adhesion, slime layer formation and delta toxin in particular have increased the percentage of true infections. Due to the lack of research on molecular detection of Staphylococcus epidermidis delta toxin and also the unknown percentage of delta toxin in neonate units of the selected university hospitals of Isfahan and Tehran in Iran, we used hld gene as a specific target for detection of mentioned toxin in the present study. Clinical invasive strains of Staphylococcus epidermidis were isolated from different sources of infections including blood culture, blood and urinary catheters, wounds and etc. Using phenotypic method 67.5% of all strains were found to have the ability to produce delta toxin in vitro while 87.5% were found to harbor hld gene in molecular test. Conversely antimicrobial susceptibility test was performed by disc diffusion method on Mueller-Hinton agar. No resistance to vancomycin was observed whereas resistance to cefoxitin (75%), oxacillin (65%) and gentamicin (62.5%) was noticeable. 相似文献

Levamisole as an immunomodulator drug has been demonstrated to improve the immune response to hepatitis B virus vaccination in haemodialysis patients. The aim of this randomized double‐blind placebo‐controlled trial was to evaluate the effect of levamisole supplementation on tetanus‐diphtheria (Td) vaccine response rates in haemodialysis patients. Forty haemodialysis patients who had not received tetanus vaccination in a year before investigation and had unprotective anti‐tetanus immunoglobulin G (IgG) levels (<0.1 international unit/mL) were enrolled and randomized into two equal groups to receive one dose of intramuscular Td vaccine supplemented with either levamisole (100 mg) or placebo daily, for 6 days before and 6 days after vaccination. The anti‐tetanus IgG levels were measured 1 and 6 months after vaccination. One month post‐vaccination, four patients were excluded from the levamisole group and two from the placebo group because of either death or renal transplantation. At 1 month, 13 out of 16 (81%) patients in the levamisole group as compared with six out of 18 (33%) patients in the placebo group developed protective anti‐tetanus IgG levels (relative risk = 2.44, 95% confidence interval (CI) = 1.21, 4.88). From 1 to 6 months post‐vaccination, one more patient in the levamisole group and two more patients in the placebo group were excluded because of renal transplantation. At 6 months, 11 out of 15 (73%) patients in the levamisole group as compared with four out of 16 (25%) patients in the placebo group still had protective anti‐tetanus IgG levels (relative risk = 2.93, 95% CI = 1.19, 7.23). Supplementation of Td vaccination with levamisole may enhance seroconversion against tetanus in haemodialysis patients. 相似文献

To investigate variations in explanations given for disparities in health care use between migrant and non-migrant groups, by clients and care providers in Sweden. Qualitative evidence collected during in-depth interviews with five ‘migrant’ health service clients and five physicians. The interview data generated three categories which were perceived by respondents to produce ethnic differences in health service use: “Communication issues”, “Cultural differences in approaches to medical consultations” and “Effects of perceptions of inequalities in care quality and discrimination”. Explanations for disparities in health care use in Sweden can be categorized into those reflecting social/structural conditions and the presence/absence of power and those using cultural/behavioural explanations. The negative perceptions of ‘migrant’ clients held by some Swedish physicians place the onus for addressing their poor health with the clients themselves and risks perpetuating their health disadvantage. The power disparity between doctors and ‘migrant’ patients encourages a sense of powerlessness and mistreatment among patients. 相似文献

We describe a boy with multiple congenital anomalies including a complex heart defect, club feet, adducted thumbs, and facial dysmorphic features. He died at the age of 2 months following cardiac surgery. G-banding analysis identified an abnormal chromosome 5q suspected to be an interstitial deletion (5)(q33q35). Breakpoints of the deleted segment were confirmed as del(5)(q33.3q35) by multicolor fluorescence in situ hybridization (FISH) using two sets of combinatorially labeled band specific YAC clones. Findings are discussed in view of previously published cases. 相似文献

Objective: An adverse drug event (ADE) is an injury resulting from a medical intervention related to a drug. The emergency department (ED) is a ward vulnerable to more ADEs because of overcrowding. Information technologies such as computerized physician order entry (CPOE) and clinical decision support system (CDSS) may decrease the occurrence of ADEs. This study aims to review research that reported the evaluation of the effectiveness of CPOE and CDSS on lowering the occurrence of ADEs in the ED. Data Sources: PubMed, EMBASE, and Web of Science databases were used to find studies published from 2003 to 2018. The search was conducted in November 2018. Study Selection and Data Extraction: The search resulted in 1700 retrieved articles. After applying inclusion and exclusion criteria, 11 articles were included. Data on the date, country, type of system, medication process stages, study design, participants, sample size, and outcomes were extracted. Data Synthesis: Results showed that CPOE and CDSS may prevent ADEs in the ED through significantly decreasing the rate of errors, ADEs, excessive dose, and inappropriate prescribing (in 54.5% of articles); furthermore, CPOE and CDSS may significantly increase the rate of appropriate prescribing and dosing in compliance with established guidelines (45.5% of articles). Conclusion: This study revealed that the use of CPOE and CDSS can lower the occurrence of ADEs in the ED; however, further randomized controlled trials are needed to address the effect of a CDSS, with basic or advanced features, on the occurrence of ADEs in the ED. 相似文献

Dopamine decreases tubular sodium reabsorption, attributed in part to Na-K-ATPase inhibition in the proximal convoluted tubule (PCT). Because the final regulation of sodium excretion occurs in the collecting duct, where specific dopamine DA1 binding sites have been demonstrated, we examined the effects of dopamine, as well as of DA1 and DA2 receptor agonists on Na-K-ATPase activity and on the number of units in Madin-Darby canine kidney (MDCK) cells, which retain differentiated properties of the renal cortical collecting tubule epithelium. Dopamine (10–5 M) inhibited pump activity (by 50%) and reduced the number of units. This effect was reproduced by the DA1 agonist SKF 38393, which inhibited pump activity in a dose- and time-dependent manner (maximum, 10–5 M). The DA2 agonist quinpirole hydrochloride was without effect, either alone or in combination with SKF 38393. Inhibition of pump activity by dopamine was totally abolished by H7 (100 M), an inhibitor of protein kinase (PK), but partially by 2, 5-dideoxyadenosine (DDA) and H4, respective inhibitors of cAMP production and PKA, which suggests that the dopamine effect on Na-K-ATPase activity may be linked to activation of both PKC and PKA. In these cells, amiloride addition during preincubation did not alter the effect of dopamine on Na-K-ATPase activity; in contrast, furosemide increased further the inhibitory effect of dopamine on the enzyme activity. Monensin addition (10–3 M) reversed the inhibitory effect of dopamine after a 30-min preincubation. These results indicate that dopamine inhibits Na-K-ATPase activity in MDCK cells and that this inhibition is mediated by activation of the DA1 receptor, they also suggest that PKC and PKA activation inhibits apical sodium entry. 相似文献
