Background Providing written medicine information to consumers enables them to make informed decisions about their medicines, playing an important role in educating and improving health literacy. In Australia, standardized written medicine information called Consumer Medicine Information (CMI) is available for medicines as package inserts, computer prints, or leaflets. Consumers want and read CMI, but may not always ask for it. General practitioners (GPs) and pharmacists are an important source of written medicine information, yet may not always provide CMI in their practice. Objective To examine and compare the awareness, use and provision of CMI by consumers, pharmacists and general practitioners (GPs). Methods Based on previous studies, structured questionnaires were developed and administered to a national sample of consumers (phone survey); community pharmacists and GPs (postal surveys) about utilization of CMI. Descriptive, comparative and logistic regression analyses were conducted. Results The respondents comprised of 349 pharmacists, 181 GPs and 1000 consumers. Two-thirds of consumers, nearly all (99%) pharmacists and 90% of GPs were aware of CMI. About 88% of consumers reported receiving CMI as a package insert, however most pharmacists (99%) and GPs (56%) reported providing computer-generated CMI. GPs' and pharmacists' main reason for providing CMI was on patient request. Reasons for not providing were predominantly because consumers were already taking the medicine, concerns regarding difficulty understanding the information, or potential non-adherence. Of the 691 consumers reportedly reading CMI, 35% indicated concerns after reading. Factors associated with reading included gender, type of CMI received and frequency of provision. Conclusion Consumers want and read information about their medicines, especially when received from their GP or pharmacist. Healthcare professionals report usually discussing CMI when providing it to patients, although continued improvements in dissemination rates are desirable. Regular use of CMI remains a challenge, and ongoing strategies to promote CMI use are necessary to improve uptake of CMI in Australia.

Peanut ( PN) and tree nuts ( TNs) are common causes of anaphylaxis in Western countries, but no information is available in Korea. To feature clinical characteristics of anaphylaxis caused by PN, TNs, and seeds, a retrospective medical record review was performed in 14 university hospitals in Korea (2009-2013). One hundred and twenty-six cases were identified, with the mean age of 4.9 years. PN, walnut ( WN), and pine nut accounted for 32.5%, 41.3%, and 7.1%, respectively. The median values of specific IgE ( sIgE) to PN, WN, and pine nut were 10.50, 8.74, and 4.61 kU
A /l, respectively. Among 50 cases managed in the emergency department, 52.0% were treated with epinephrine, 66.0% with steroid, 94.0% with antihistamines, 36.0% with oxygen, and 48.0% with bronchodilator. In conclusion, WN, PN, and pine nut were the three most common triggers of anaphylaxis in Korean children, and anaphylaxis could occur at remarkably low levels of sIgE.

Mesenchymal stem cell therapy is a promising candidate for the treatment of systemic lupus erythematosus (SLE). To exert their efficacy fully, mesenchymal stem cells must infiltrate efficiently into the lesion sites. Here, we examined the role of CXCR3 in mesenchymal stem cell infiltration into the kidney of MRL.Fas
lpr mice, which highly expressed CXCL10. The phenotypes, production of immunosuppressive mediators, and capacity to inhibit T and B cells of CXCR3-deficient mesenchymal stem cells were similar to those of wild-type mesenchymal stem cells. However, they showed less infiltration into the nephritic kidney, less conjugation with endothelial cells and weaker MMP-9 expression than did wild-type mesenchymal stem cells. Consequently, CXCR3-deficient mesenchymal stem cells did not ameliorate lupus symptoms in MRL.Faslpr mice in comparison with wild-type mesenchymal stem cells. In summary, our data suggest that upregulation of CXCR3 in mesenchymal stem cells will be a good strategy to increase their infiltration into the kidney, which will improve therapeutic outcomes in SLE.

Summary: Background: Little is known about factors affecting the quality of life (QoL) of patients with vitiligo, and previous studies have shown conflicting results. Objectives: To explore the QoL of patients with vitiligo and to identify factors affecting QoL. Methods: A nationwide questionnaire‐based study was conducted with 1123 patients with vitiligo recruited from 21 hospitals in Korea from July 2015 to June 2016. Data were collected using a structured questionnaire for demographic information and the Skindex‐29 instrument. Mild or severely impaired QoL in patients with vitiligo was assessed according to each domain (symptoms, functioning and emotions) of Skindex‐29. Multivariate logistic regression analyses were performed to determine the factors associated with QoL. Results: Of the enrolled participants, 609 were male and 514 female, with a mean age of 49·8 years (range 20–84). The median duration of disease was 3·0 years (range 0–60). Using multivariate logistic regression modelling, the involvement of visible body parts and a larger affected body surface area were consistently associated with QoL impairment in all three domains of Skindex‐29. Additionally, the QoL of patients aged 20–59 years, who potentially had a more active social life than older patients, was associated with functional impairment. Furthermore, a higher educational background was associated with emotional impairment. Conclusions: A multitude of factors significantly influence the QoL of patients with vitiligo. A better appreciation of these factors would help the management of these patients. [ABSTRACT FROM AUTHOR]

Purpose: Injection of adipose tissue-derived stem cells (ASCs) is a novel method for the treatment of complex perianal fistulas. We aimed to evaluate the safety and efficacy of ASCs in the treatment of complex anal fistulas not associated with Crohn's disease. Methods: A phase II clinical trial was performed comparing two different doses of ASCs (group 1: 1 × 10 cells/mL and group 2: 2 × 10 cells/mL). Eligible patients were administered an amount of ASCs proportional to the length of the fistula by injection into the submucosal layer surrounding the internal opening and inside of the fistula tract. ASCs at twice the initial concentration were administered if complete closure was not achieved within 8 weeks. The efficacy endpoint was the complete closure of fistulas 8 weeks after injection. Patients demonstrating complete closure at week 8 were subjected to follow-up for 6 months. Results: Fifteen patients were injected with ASCs; thirteen completed the study. Complete closure was observed in 69.2% (9/13) of patients at 8 weeks. Three of five patients in group 1, and six of eight in group 2 displayed complete closure; no significant differences were observed between the groups. Six of nine patients who showed complete closure participated in additional follow-up; five (83.3%) showed persistent response at 6 months. No grade 3 or 4 adverse events (AEs) were observed; observed AEs were not related to ASC treatment. Conclusion: ASCs might be a good option for the treatment of complex perianal fistulas are not healed by conventional operative procedures. [ABSTRACT FROM AUTHOR]

Recent meta-analysis by the Cochrane collaboration concluded that treatment of varicocele may improve an infertile couple's chance of pregnancy. However, there has been no consensus on the management of subclinical varicocele. Therefore, we determine the impact of varicocele treatment on semen parameters and pregnancy rate in men with subclinical varicocele. The randomised controlled trials that assessed the presence and/or treatment of subclinical varicocele were included for systematic review and meta-analysis. Random effect model was used to calculate the weighted mean difference of semen parameters and odds ratio of pregnancy rates. Seven trials with 548 participants, 276 in subclinical varicocelectomy and 272 in no-treatment or clomiphene citrate subjects, were included. Although there was also no statistically significant difference in pregnancy rate ( OR 1.29, 95% CI 0.99-1.67), surgical treatment resulted in statistically significant improvements on forward progressive sperm motility ( MD 3.94, 95% CI 1.24-6.65). However, the evidence is not enough to allow final conclusions because the quality of included studies is very low and further research is needed. [ABSTRACT FROM AUTHOR]

Expiratory muscle strength training ( EMST) involves forcible blowing as a means of generating high expiratory pressure, against adjustable resistance. EMST has recently been introduced as a potential treatment for dysphagia. This study was performed to investigate the effects of EMST on the activity of suprahyoid muscles, aspiration and dietary stages in stroke patients with dysphagia. Twenty-seven stroke patients with dysphagia were randomly divided into two groups. The experimental group performed EMST with a 70% threshold value of maximal expiratory pressure, using an EMST device, 5 days a week for 4 weeks. The placebo group trained with a sham device. The EMST regime involved 5 sets of 5 breaths through the EMST device for a total of 25 breaths per day. Activity in the suprahyoid muscle group was measured using surface electromyography ( sEMG). Further, the penetration-aspiration scale ( PAS) was used to assess the results of the videofluoroscopic swallowing study ( VFSS). In addition, dietary stages were evaluated using the Functional Oral Intake Scale ( FOIS). The experimental group exhibited improved suprahyoid muscle group activity and PAS results, when compared to the placebo group. Following intervention, statistical analysis indicated significant differences in measured suprahyoid muscle activity ( P = 0·01), liquid PAS outcomes ( P = 0·03) and FOIS results ( P = 0·06), but not semisolid type PAS outcomes ( P = 0·32), between the groups. This study confirms EMST as an effective treatment for the development of suprahyoid muscle activity in stroke patients with dysphagia. Additionally, improvements in aspiration and penetration outcomes were observed. [ABSTRACT FROM AUTHOR]

Background The beneficial effect of biofeedback therapy ( BFT) over a period of more than 2 years has not been studied in a large group of patients. The aim of this study was to evaluate the long-term efficacy of BFT for dyssynergic defecation ( DD). Methods We evaluated the results for 347 consecutive constipated patients with DD who underwent BFT for a median of five sessions between 2004 and 2009. Initial responses were assessed immediately after the completion of BFT. A responder was defined as a subject with at least a three-point improvement from before to after BFT on an 11-point global bowel satisfaction ( GBS) scale, or a two-point improvement if the baseline GBS was more than six points. The probability of remaining a responder was estimated by non-parametric maximum likelihood estimation. Key Results The initial response rate to BFT was 72.3% ( n = 251), Parkinson's disease and higher baseline GBS scores were associated with initial non-response. The long-term efficacy of BFT was analyzed in 103 patients who were followed up for more than 6 months; the initial effects of BFT were maintained in 85 of the patients (82.5%) during a median of 44 months of follow-up ( IQR = 12-68). The probability of remaining a responder was 60% at 2 years, and 58% at 5 years. Conclusions & Inferences The efficacy of BFT is maintained for more than 2 years after BFT in a considerable proportion of constipated patients with DD. BFT is effective and durable treatment for managing DD. [ABSTRACT FROM AUTHOR]

Rhabdomyolysis is a pathological syndrome caused by skeletal muscle cell damage that affects the integrity of the cellular membrane and leads to the release of toxic intracellular constituents into the bloodstream. Although cytomegalovirus ( CMV) has rarely been reported as a cause of rhabdomyolysis, CMV infection could be considered as a possible cause because of its clinical significance in kidney transplant recipients ( KTRs). We report 2 cases of rhabdomyolysis associated with CMV infection in KTRs. A 64-year-old woman (Case 1) and a 65-year-old man (Case 2), who had each received a kidney from a living unrelated donor, were admitted with complaints of weakness in both legs and myalgia. Laboratory findings revealed highly increased creatine phosphokinase and myoglobinuria. In both cases, no recent alterations of medications had occurred, and other causes of rhabdomyolysis-such as trauma, alcohol, drugs, and electrolyte abnormalities - were excluded. CMV pp65 antigen was positive, and patients were diagnosed with rhabdomyolysis associated with CMV infection. Both patients recovered without complications after ganciclovir treatment. In conclusion, CMV infection should be considered as a possible cause of rhabdomyolysis in KTRs. [ABSTRACT FROM AUTHOR]

Summary: The administration of teriparatide (TPTD) in conjunction with periodontal care could provide faster and more favorable clinical outcomes in previously refractory bisphosphonate-related osteonecrosis of the jaws (BRONJ) cases compared to conventional dental care, combination of surgery and antimicrobial treatment. We also found that underlying vitamin D levels might influence the response to TPTD treatment. Introduction: Treatment of BRONJ is quite challenging and there are no standard treatment modalities. In this retrospective, longitudinal study, we examined whether additional TPTD administration could be beneficial for the resolution of BRONJ lesions compared to conservative management, such as antimicrobial treatment with or without surgery, and also studied the factors influencing the response to TPTD. Methods: Twenty-four cases of intractable BRONJ were included: 15 subjects were assigned to the TPTD group and the other 9 subjects, who refused TPTD administration, were assigned to the non-TPTD group. All subjects in both groups continued calcium and vitamin D supplementation and the TPTD group additionally received a daily subcutaneous injection of 20 μg TPTD for 6 months. Results: While 60.0 % of the non-TPTD group showed one stage of improvement in BRONJ, 40.0 % of the group did not show any improvement in disease status. In the TPTD group, 62.5 % of the treated subjects showed one stage of improvement and the other 37.5 % demonstrated a marked improvement, including two stages of improvement or complete healing, and there was not a single case that did not improve. The clinical improvement of BRONJ was statistically better in the TPTD group after the 6-month treatment ( p < 0.05). Moreover, patients with higher baseline serum 25(OH)D levels showed better clinical therapeutic outcomes with TPTD. Conclusions: We observed the beneficial effects of TPTD on BRONJ, and subjects with optimal serum vitamin D concentrations seemed to reap the maximum therapeutic effects of TPTD. A prospective, randomized, controlled trial should be needed to further evaluate the therapeutic efficacy of TPTD in the resolution of BRONJ. [ABSTRACT FROM AUTHOR]

Background Written medicine information can play an important role in educating consumers about their medicines. In Australia, standardised, comprehensive written information known as Consumer Medicine Information (CMI) is available for all prescription medicines. CMI is reportedly under-utilised by general practitioners (GPs) and community pharmacists in consultations, despite consumer desire for medicine information. This study aimed to determine consumers', GPs' and community pharmacists' preferences for CMI provision and identify barriers and facilitators to its use. Method Structured questionnaires were developed and administered to a national sample of Australian consumers (phone survey), community pharmacists and GPs (postal surveys) surrounding utilisation of CMI. Descriptive and comparative analyses were conducted. Results Half of consumers surveyed wanted to receive CMI for their prescription medicine, with spoken information preferable to written medicine information for many consumers and healthcare professionals. GPs and pharmacists remained a preferred source of medicine information for consumers, although package inserts were appealing to many among all three cohorts. Overall pharmacists were the preferred provider of CMI primarily due to their medicine expertise, accessibility and perceived availability. GPs preferred CMI dissemination through both the GP and pharmacist. Some consumers preferred GPs as the provider of medicines information because of their knowledge of the patients' medicines and/or medical history, regularity of seeing the patient and good relationship with the patient. Common barriers to CMI provision cited included: time constraints, CMI length and perceptions that patients are not interested in receiving CMI. Facilitators to enhance provision included: strategies to increase consumer awareness, longer consultation times and counseling appointments, and improvements to pharmacy software technology and workflow. Conclusion Medicine information is important to consumers, whether as spoken, written or a combination of both. A tailored approach is needed to ascertain individual patient preference for delivery and scope of medicine information desired so that appropriate information is provided. The barriers of time and perceived attitudes of healthcare practitioners present challenges which may be overcome through changes to workplace practices, adoption of identified facilitators, and education about the positive benefits of CMI as a tool to engage and empower patients.

Summary: Bazedoxifene and raloxifene were evaluated in the treatment of postmenopausal osteoporosis from health economic perspective in Europe. Based on a computer-based algorithm calculating efficacy of the treatments, bazedoxifene appears to be a cost-effective strategy compared to raloxifene, particularly in patients at high fracture risk. Introduction: The purpose of this study was to compare cost-effectiveness of bazedoxifene and raloxifene in eight European countries: Belgium, France, Germany, Ireland, Italy, Spain, Sweden, and the UK. Methods: The Fracture Risk Assessment Tool, which is a computer-based algorithm to calculate fracture probability using clinical risk factors alone or with bone mineral density, was incorporated in a Markov Tunnel model to evaluate cost-effectiveness of bazedoxifene 20 or 40 mg vs. raloxifene 60 mg in postmenopausal osteoporotic women. The efficacy of bazedoxifene and raloxifene for vertebral and non-vertebral fractures was measured as a function of the 10-year probability of a major osteoporotic fracture. The model estimated the incremental cost-effectiveness ratio and net monetary benefit (NMB) from a healthcare perspective, given the willingness to pay €30,000. Results: In postmenopausal osteoporotic women, bazedoxifene was a cost saving strategy compared to raloxifene in the countries studied. The median NMB of bazedoxifene compared to raloxifene increased monotonically with the 10-year fracture probability. In general, the median NMB became greater than 0 in women with 10-year probabilities of a major osteoporotic fracture between 5 and 10 % or above. The impact on results by varying the assumptions in the model was examined in sensitivity analysis. Conclusion: Bazedoxifene appears to be a cost-effective strategy compared to raloxifene for the treatment of postmenopausal osteoporotic women in Europe, particularly in patients at high fracture risk.

Summary: The existence of local osteoporosis necessitates patient-specific analysis. Lower and higher ranges of local buckling ratio were found at femoral necks for adequate and inadequate drug response groups, respectively (grouped based on fracture loads). Management of hip fracture risk should be targeted at local geometric abnormalities causing instability. Introduction: Hip fracture amongst the elderly is a growing concern especially with improvements in living standards and increasing lifespan. Approximately half of the total hip fractures result from those without osteoporosis. This escalates the need to observe local osteoporosis. By observing the local buckling ratio (BR) in the femoral neck in ten risedronate-treated subjects over 3 years, we discovered that subjects with improved fracture loads, as predicted by finite element (FE) analysis, were associated with lower local BR and vice versa. Methods: The 3D models of the left proximal femurs were generated, and local BR values at 30° intervals were obtained from femoral neck slices by measuring the respective mean cortical thickness and mean outer radius. Following geometric analysis, structural strength was examined with FE analysis where critical fracture loads ( Fcr) were acquired from sideways fall load simulations. Results: We classified subjects in three groups according to the change in Fcr: adequate (+20 %), inadequate (−22 %) and indefinite (−2 %) drug response groups. A common striking feature was that lower and higher ranges of local BR values (baseline year) were found for adequate (min = 2.14, max = 8.04) and inadequate (min = 1.72, max = 11.38) drug response groups, respectively. Conclusions: Subjects in the inadequate drug response group exhibited high local BR at the supero-anterior and supero-posterior regions. These high local BR values coincided with FE-predicted critical strain regions, whereas subjects from the adequate drug response group showed significantly reduced strain regions. The superiority of coupling geometry (BR) with structure ( Fcr) over bone mineral density measurements alone by monitoring local osteoporosis has been illustrated. [ABSTRACT FROM AUTHOR]

This study was performed to assess the efficacy of beraprost sodium ( BPS) in painful diabetic peripheral neuropathy ( DPN) in type 2 diabetes mellitus ( T2DM) patients. In this randomized clinical trial, 99 T2DM patients (41% male, age 60 ± 6 years) with DPN but without evidence of peripheral artery disease were randomized to receive either BPS (40 µg, tid) or placebo for 8 weeks. The primary end point was the improvement of the total symptom score ( TSS), temperature rebound ( TR) and nadir to peak ( NP) above baseline. After 8 weeks treatment, the change of TSS in the BPS group showed a significant improvement compared to the placebo group (2.80 ± 2.48 vs. 1.60 ± 1.94 points, p = 0.009). Furthermore, the number of patients who showed signs of improvement in TSS and the proportion of patients with 50% relief of symptom was also significantly greater in the BPS group than in the placebo group (83.7 vs. 62%, p = 0.015, 36.2 vs. 14%, p = 0.009, respectively). In conclusion, treatment with BPS significantly improved TSS over an 8-week period. [ABSTRACT FROM AUTHOR]

The responses to numerous stress signals are important for cellular growth and survival. The p53 tumor-suppressor protein is stabilized under stress conditions and induces transcription of several genes to regulate cell cycle and apoptosis. Regarding p53 protein accumulation, inhibition of proteasomal degradation of p53 protein, which is mainly mediated by Mdm2, has received much attention. Here, we demonstrate that regulation of translation initiation is also crucial for p53 protein accumulation. Furthermore, we report that heterogeneous nuclear ribonucleoprotein (hnRNP) Q binds to the 5′-untranslated region (UTR) of mouse p53 mRNA and regulates translation efficiency of p53 and apoptosis progression. We also suggest that changes in cytosolic hnRNP Q levels contribute to cell cycle-dependent translational differences in p53 mRNA. [ABSTRACT FROM AUTHOR]

J Periodont Res 2012; 47: 800-810. © 2012 John Wiley & Sons A/S Background and Objective: Polycan is a promising candidate for the treatment of periodontal disease. This study was undertaken to examine whether Polycan, a type of β-glucan, has a protective effect on ligature-induced experimental periodontitis and related alveolar bone loss in Sprague-Dawley rats. Material and Methods: Polycan was orally administered, daily, for 10 d, at 21.25, 42.5 or 85 mg/kg, beginning 1 d after ligation. Changes in body weight and alveolar bone loss were monitored, and the anti-inflammatory effects of Polycan were determined by measuring the levels of myeloperoxidase (MPO), interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in gingival tissue. We also evaluated inducible nitric oxide synthase (iNOS) activity and malondialdehyde (MDA) concentrations as a measure of the antioxidant effect. Results: Ligature placement led to a marked decrease in body weight, increased alveolar bone loss and increased concentrations of MPO, IL-1β, TNF-α and MDA, as well as increased iNOS activity and inflammatory cell infiltration and decreased collagen-fiber content. Histological examination revealed increases in the number and activity of osteoclast cells, decreases in alveolar bone volume and elevated percentages of osteclasts on the alveolar bone surface. Daily oral treatment with 42.5 or 85 mg/kg of Polycan for 10 d led to significant, dose-dependent inhibition of the effect of ligature placement. Conclusion: Taken together, these results suggest that 10 d of oral treatment with Polycan effectively inhibits ligature placement-induced periodontitis and related alveolar bone loss via an antioxidant effect.

Abstract Aim This article presents a case report of autogenous tooth transplantation to a site which had insufficient bone volume using a sinus lift and allogenic bone graft. Summary An ectopic, fully impacted premolar tooth was autotransplanted from its ectopic impaction site into its original site, where there was insufficient recipient vertical bone volume because of sinus expansion. The deciduous tooth was extracted from the recipient site, and the sinus membrane detached and elevated via the alveolar socket. Allogenic bone grafting was performed, and the impacted premolar was transplanted into the prepared site. To improve adaptation, the recipient site was prepared using a rapid prototype tooth model, a replica tooth which allowed complete socket preparation in advanced of the actual removal of the donor tooth. The donor tooth was fixed with sutures and maintained for 17 days to allow physiologic movement. Root canal treatment was initiated 24 days after autotransplantation, and an intra-canal medicament was used for 4 months. Canal filling was completed 5 months after autotransplantation. There was no root resorption of the transplanted tooth, and the grafted bone was well preserved and had no signs of infection. Key learning points [ABSTRACT FROM AUTHOR]

In experimental and clinical research, it is difficult to directly measure responses in the human body, such as contact pressure and stress in a joint, but finite element analysis (FEA) enables the examination of in vivo responses by contact analysis. Hence, FEA is useful for pre-operative planning prior to orthopaedic surgeries, in order to gain insight into which surgical options will result in the best outcome. The present study develops a numerical simulation technique based on FEA to predict the surgical outcomes of osteotomy methods for the treatment of slipped capital femoral epiphyses. The correlation of biomechanical parameters including contact pressure and stress, for moderate and severe cases, is investigated. For severe slips, a base-of-neck osteotomy is thought to be the most reliable and effective surgical treatment, while any osteotomy may produce dramatic improvement for moderate slips. This technology of pre-operative planning using FEA can provide information regarding biomechanical parameters that might facilitate the selection of optimal osteotomy methods and corresponding surgical options.

Sodium bicarbonate may be added to rocuronium to decrease pain on injection. However, this mixture may result in the formation of carbon dioxide bubbles. We investigated whether the addition of sodium bicarbonate to rocuronium alters neuromuscular blockade, in 120 patients randomly assigned to receive rocuronium mixed with saline or bicarbonate 8.4%, either in varying doses (for dose-response measurements; 60 patients) or a fixed dose of 600 μg.kg-1 (for time-course measurements; 60 patients). Sodium bicarbonate resulted in a left-shift of the rocuronium dose-response curve. The effective doses of rocuronium to produce 95% twitch depression were 331.6 (95% CI: 310.4–352.8) and 284.3 (95% CI: 262.0–306.6) μg.kg−1 mixed with isotonic saline or sodium bicarbonate, respectively (p < 0.001). The mean (SD) onset times of rocuronium 600 μg.kg-1 were 3.6 (0.6) and 2.7 (0.5) min in the corresponding groups, respectively (p < 0.001). The mean (SD) times to 95% recovery were 35.8 (5.8) and 47.9 (7.1) min, respectively (p < 0.001). We conclude that the mixing of sodium bicarbonate with rocuronium enhances the potency, shortens the onset and prolongs the duration of action. [ABSTRACT FROM AUTHOR]

Most acute infections with RNA viruses are transient and subsequently cleared from the host. Recent evidence, however, suggests that the RNA virus, West Nile virus (WNV), not only causes acute disease, but can persist long term in humans and animal models. Our goal in this study was to develop a mouse model of WNV persistence. We inoculated immunocompetent mice subcutaneously (s.c.) with WNV and examined their tissues for infectious virus and WNV RNA for 16 months (mo) post-inoculation (p.i.). Infectious WNV persisted for 1 mo p.i. in all mice and for 4 mo p.i. in 12% of mice, and WNV RNA persisted for up to 6 mo p.i. in 12% of mice. The frequency of persistence was tissue dependent and was in the following order: skin, spinal cord, brain, lymphoid tissues, kidney, and heart. Viral persistence occurred in the face of a robust antibody response and in the presence of inflammation in the brain. Furthermore, persistence in the central nervous system (CNS) and encephalitis were observed even in mice with subclinical infections. Mice were treated at 1 mo p.i. with cyclophosphamide, and active viral replication resulted, suggesting that lymphocytes are functional during viral persistence. In summary, WNV persisted in the CNS and periphery of mice for up to 6 mo p.i. in mice with subclinical infections. These results have implications for WNV-infected humans. In particular, immunosuppressed patients, organ transplantation, and long term sequelae may be impacted by WNV persistence. [ABSTRACT FROM AUTHOR]

Diabet. Med. 27, 30–36 (2010) Aims We examined the effect of rosiglitazone on insulin sensitivity, abdominal fat and mid-thigh intramuscular fat distribution, and plasma concentrations of adipocytokines in patients with Type 2 diabetes. Methods Rosiglitazone was administered at a daily dose of 4 mg to 42 Type 2 diabetes patients [age 32–70 years, body mass index (BMI) 17.5–32.6 kg/m
2 , 15 women, 27 men] for 12 weeks. Various anthropometric and metabolic profiles, plasma adiponectin, leptin, and resistin levels were measured, and insulin resistance was calculated from the short insulin tolerance test. Body fat composition was assessed by computed tomography. Results Twelve weeks’ rosiglitazone treatment resulted in improved insulin resistance despite increases in body weight and BMI. There was a significant decrease in abdominal visceral adipose tissue area (145 ± 65.6 vs. 129 ± 73.1 cm2 , P = 0.049). Mid-thigh low-density muscle area (TLDMA) increased from 23 ± 9.6 to 26 ± 8.2 cm2 ( P = 0.009). There were significant changes in plasma adipocytokines, but they were not significantly correlated with changes in insulin resistance. Conclusions Rosiglitazone treatment resulted in an improvement of insulin responsiveness in Type 2 diabetic subjects, which was associated with the redistribution of visceral and subcutaneous adipose tissue, an increase in TLDMA, and changes in serum adipocytokine levels. Further studies are needed to elucidate the insulin sensitizing mechanism of rosiglitazone on peripheral skeletal muscles. [ABSTRACT FROM AUTHOR]- Published

Abstract: The idiopathic inflammatory myopathies (IIM) comprise a heterogeneous group of muscle diseases. The three best-studied subgroups are dermatomyositis (DM), polymyositis (PM) and sporadic inclusion body myositis (IBM). The latter represents a steroid-refractory condition. PM and IBM are characterized by a cell-mediated immune response directed against non-necrotic fibers expressing Major Histocompatibility Complex class I (MHC class I). IBM presents with additional degenerative features, including rimmed vacuoles and depositions of aberrant proteins. DM is a complement-mediated endotheliopathy often accompanied by characteristic skin manifestations. The ubiquitously expressed transcription factor NF-κB is considered essential for the development of auto-immunity. This review describes data gathered so far concerning the distribution of the classical heterodimer p65/p50 and its inhibitor I-κBα in IIM skeletal muscle. Data suggest that the NF-κB complex plays a role in the endotheliopathy characterizing DM and might be involved in myofiber regeneration, and appoint CD4+ and CD68+ mononuclear cells with a more prominent role than previously assumed. Fragmentary knowledge of the immunopathogenesis of IIM hampers the development of therapeutic strategies suited to all patient groups. Unravelling the precise involvement of NF-κB subunits in IIM immunopathogenesis can shed new light onto the etiology of these diseases and may offer a novel therapeutic target.

Background/Aims: p12
DOC-1 is a well-known growth suppressor; however, its role in gastric carcinogenesis is still unclear. We investigated the expression of p12DOC-1 in gastric cancer tissues and its possible correlation with p53 expression, and determined its clinical significance. Methods: Immunohistochemical staining using the tissue array method was performed on 180 human gastric carcinomas. The clinicopathological features and prognostic significance were analyzed. Results: Of the 180 tissue samples, p53 expression was positive in 85 (47.2%) and p12DOC-1 expression was negative in 140 (77.8%). The negative expression of p12DOC-1 was significantly associated with a more advanced depth of tumor invasion and stage (p < 0.05). No apparent correlation was found between p12DOC-1 and p53 expressions. The 5-year survival rate of the p12DOC-1 -positive cases (53.7%) was higher than that of the p12DOC-1 -negative cases (39.3%); however, neither p12DOC-1 nor p53 expression status had any statistically significant prognostic value. Multivariate analysis revealed that lymph node metastasis, distant metastasis, lymphatic invasion and perineural invasion were independent prognostic factors. Conclusions: This is the first report that suggests that p12DOC-1 may be involved in the development and progression of gastric cancer. Further studies are required to clarify its exact role in the mechanism of gastric carcinogenesis. Copyright © 2009 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]- Published

Background and purpose:Recently, we reported that 12(S)-HPETE (12(S)-hydroperoxyeicosa-5Z,8Z,10E,14Z-tetraenoic acid) induces scratching in ICR mice. We hypothesized that 12(S)-HPETE might act as an agonist of the low-affinity leukotriene B
4 receptor BLT2 . To confirm the involvement of the BLT2 receptor in 12(S)-HPETE-induced scratching, we studied the scratch response using the BLT2 receptor agonists compound A (4′-{[pentanoyl (phenyl) amino]methyl}-1,1′-biphenyl-2-carboxylic acid) and 12(S)-HETE (12(S)-hydroxyeicosa-5Z,8Z,10E,14Z-tetraenoic acid).Experimental approach:A video recording was used to determine whether the BLT2 receptor agonists caused itch-associated scratching in ICR mice. Selective antagonists and several chemicals were used.Key results:Both 12(S)-HETE and compound A dose dependently induced scratching in the ICR mice. The dose–response curve for compound A showed peaks at around 0.005–0.015 nmol per site. Compound A- and 12(S)-HETE-induced scratching was suppressed by capsaicin and naltrexon. We examined the suppressive effects of U75302 (6-[6-(3-hydroxy-1E,5Z-undecadienyl)-2-pyridinyl]-1,5-hexanediol, the BLT1 receptor antagonist) and LY255283 (1-[5-ethyl-2-hydroxy-4-[[6-methyl-6-(1H-tetrazol-5-yl)heptyl]oxy]phenyl]-ethanone, the BLT2 receptor antagonist) on the BLT2 agonist-induced scratching. LY255283 suppressed compound A- and 12(S)-HETE-induced scratching, but U75302 did not. LY255283 required a higher dose to suppress the compound A-induced scratching than it did to suppress the 12(S)-HETE-induced scratching. One of the BLT2 receptor agonists, 12(R)-HETE (12(R)-hydroxyeicosa-5Z,8Z,10E,14Z-tetraenoic acid), also induced scratching in the ICR mice.Conclusions and implications:Our present results corroborate the hypothesis that the BLT2 receptor is involved in 12(S)-lipoxygenase-product-induced scratching in ICR mice. We also confirmed that this animal model could be a valuable means of evaluating the effects of BLT2 receptor antagonists.British Journal of Pharmacology (2008) 154, 1073–1078; doi:10.1038/bjp.2008.220; published online 9 June 2008 [ABSTRACT FROM AUTHOR]- Published

Anti-tumor-associated glycoprotein (TAG)-72 PEG-immunoliposomes (PILs) were prepared by conjugation of Fab′ fragments of recombinant humanized monoclonal antibody, HuCC49, to sterically stabilize unilamellar liposomes (90–110 nm in diameter) to target TAG-72-overexpressing cancer cells. The liposomes consisted of 1-palmitonyl-2-oleoyl-sn-glycerol-3-phosphocholine (POPC), 92 mol percent, O,O′-dymyrisyl-N-lysyl aspartate (DMKD cationic lipid), 4 mol percent, distearoyl-phosphatidyl-ethanolamine-polyethylene glycol 2000 (DSPE-PEG2000), 3 mol percent and DSPE-maleimide (DSPE-PEG2000-Mal), 1 mol percent. These anti-TAG-72 PILs were able to adhere to the surface of TAG-72-overexpressing LS174 T human colon cancer cells more effectively than conventional liposomes. Also, in vitro gene transfection of the LS174 T cells by the anti-TAG-72 PILs in the presence of a high concentration of fetal bovine serum (up to 60%) was greater than that by conventional cationic lipoplexes. Intravenously administered anti-TAG-72 PILs efficiently localized in the LS174 T tumor tissues, while the non-targeted conventional liposomes did not. Intravenous administration of the anti-TAG-72 PILs containing plasmids encoding antiangiogenic proteins, such as angiostatin K1/3, endostatin and saxatilin, significantly inhibited in vivo growth of LS174 T tumors and angiogenesis in the tumor tissues. These results demonstrated the potential of TAG-72-mediated targeting of immunoliposomes as a modality for systemic gene delivery to human colon cancer cells.Cancer Gene Therapy (2008) 15, 331–340; doi:10.1038/cgt.2008.11; published online 29 February 2008 [ABSTRACT FROM AUTHOR]

Background Pimecrolimus cream 1% has been shown to effectively control atopic eczema (AE) when applied twice daily from the first signs or symptoms of AE until clearance. Moreover, pimecrolimus cream 1% has a favourable safety profile, lacking topical corticosteroid-related side-effects such as skin atrophy, making it particularly useful to treat delicate body regions (e.g. the face). Objective The objective of this naturalistic study was to monitor the safety, tolerability and efficacy of pimecrolimus when used in the long-term management of AE in a real-life setting. Methods A multicentre, open-label study was conducted in 2034 patients aged ≥ 3 months with mild to moderate AE for up to 12 months’ duration. Patients applied pimecrolimus cream twice daily, initiating treatment at first signs or symptoms of AE, continuing until clearance. Results Patients ( n= 1847; 91%) completed 3 months of the study. Treatment success (clear or almost clear AE) after 3 months of treatment was observed on the whole body in 59% of patients and on the face in 81% of patients. Disease improvement of whole body and face was seen in 77% and 63% of patients, respectively. Pruritus was absent or mild in 79% of patients. Pimecrolimus cream was well tolerated throughout the study. Conclusion In a daily practice setting, pimecrolimus cream 1% effectively and safely controls AE. [ABSTRACT FROM AUTHOR]

This study was carried out to determine whether polymorphisms of organic anion-transporting polypeptide 1B1 (OATP1B1) have an effect on rosuvastatin pharmacokinetics in Koreans. Among 200 subjects genotyped for OATP1B1 c.388A>G, and c.521T>C, 30 subjects were selected for the rosuvastatin pharmacokinetic study. The area under the concentration–time curve for 0 to infinity (AUC
0–∞ ) of rosuvastatin for group 1 (*1a/*1a, *1a/*1b, *1b/*1b), group 2 (*1a/*15, *1b/*15), and group 3 (*15/*15) were 111±49.3, 126±45.2, and 191±31.0 ng h/ml, respectively, with significant differences among the three groups (P=0.0429) and between *15/*15 and the other groups (P=0.0181). The maximum plasma concentration (Cmax ) also showed a significant difference between *15/*15 and the other groups (P=0.0181). There were no significant differences in rosuvastatin-lactone pharmacokinetics among the three groups. The pharmacokinetic exposure of rosuvastatin was higher in the OATP1B1*15/*15 subjects than the others, suggesting a potential association between the OATP1B1 genetic polymorphisms and altered rosuvastatin pharmacokinetics in Korean populations.Clinical Pharmacology & Therapeutics (2008) doi:10.1038/sj.clpt.6100267 [ABSTRACT FROM AUTHOR]- Published

Chronic myelomonocytic leukaemia (CMML) is a preleukaemic condition with myeloproliferative features, and classified as a part of myelodysplastic syndrome (MDS). Other than alkylating agents and topoisomerase II inhibitors, there is less evidence that chemotherapeutic drugs are associated with therapy-related CMML, acute leukaemia or MDS. We present a patient who developed CMML within 2 years of platinum-based chemotherapy for a metastatic non-small cell lung cancer. He received a cumulative dose of 240 mg/m2 of cisplatin, and 1123 mg/m2 of carboplatin before developing CMML. The cytogenetic study revealed trisomy 8. This is the first reported case that links platinum-based therapy with development of CMML with trisomy 8. Although the relationship between platinum therapy and the development of CMML is difficult to assess due to combinational nature of therapy in most cases, physicians should consider the possibility of CMML in patients with symptoms or signs suggestive of haematologic malignancy after platinum therapy.

HLA-matched UC blood-derived multipotent stem cells were directly transplanted into the injured spinal cord site of a 37-year-old female patient suffering from spinal cord injury (SPI). In this case, human cord blood (UCB)-derived multipotent stem cells improved sensory perception and movement in the SPI patient's hips and thighs within 41 days of cell transplantation. CT and MRI results also showed regeneration of the spinal cord at the injured site and some of the cauda equina below it. Therefore, it is suggested that UCB multipotent stem cell transplantation could be a good treatment method for SPI patients. [ABSTRACT FROM AUTHOR]

This study was conducted to evaluate the efficacy of capecitabine and to identify the subgroup of patients who would potentially have benefit from capecitabine monotherapy in patients with anthracycline- and taxane-pretreated MBC. Female patients with MBC who had been previously treated with anthracycline and taxane received oral capecitabine 2500 mg/m
2 divided in two doses daily for 2 wk with 1-wk rest period. Between September, 1999, and December, 2002, a total of 38 patients were enrolled. Among the 36 evaluable patients, one patient achieved a complete response (CR), 9 patients had partial responses (PRs), and 13 patients had stable diseases (SDs). Response rate was 26% [95% confidence interval (CI), 12–40%] and the tumor control rate (TCR, CR+PR+SD) was 61% (95% CI, 45–77%). The median follow-up duration was 27.8 mo. The median duration of response was 8.9 mo, the median time to progression was 4.6 mo, and the median overall survival was 18.1 mo. The major toxicities were hand-foot syndrome, diarrhea, and emesis. There was no treatment-related death. The predictors of better overall survival were positivity of hormone receptor, disease-free survival longer than 1 yr, non-refractoriness to anthracycline, and fewer number (≤3) of involved organs. Capecitabine monotherapy is effective and well tolerated for MBC patients who had previously been treated with anthracycline and taxane. The TCR could predict overall survival as well as the objective respose in this study, suggesting a possible role of TCR as a surrogate marker for survival in MBC patients on salvage chemotherapy. The patients who have relatively slow growing tumor and less tumor burden could have benefit from capecitabine monotherapy following anthracycline- and taxane-based chemotherapy.

The article presents information on biliary intervention for cholangiocarcinoma. Although the prognosis of patients with cholangiocarcinoma after surgical resection is variable and depends on growth characteristics and stages, complete surgical resection offers the best possibility of a cure. However, about 56% to 81 % of patients have unresectable cholangiocarcinoma because they have an advanced stage tumor or are in an inoperable condition due to bile duct obstruction. Therefore, palliative treatments for resolving jaundice are essential in these patients to improve survival length and quality.

The emerging role of the advanced practice nurse (APN) as a palliative care provider is gaining increased recognition in the United States. The APN's ability to perform comprehensive physical evaluations, order and interpret diagnostics, and prescribe appropriate medications while receiving reimbursement allow this provider to become a valuable and important discipline in the patient's plan of care. APNs consistently demonstrate an ongoing commitment to the care of the frail, poor, culturally diverse, nursing home, and rural populations—areas in which palliative care is often unavailable. This paper provides an overview of the APN's role and the ability to integrate palliative interventions into traditional health care settings. It highlights reimbursement issues and describes a case example to demonstrate how the APN can provide continuity, coordination, and reimbursement of services for the patient living with and dying from advanced illness.

The in vitro and in vivo antitumor activity of a new antitumor platinum complex, cis-malonato[(4R, 5R)-4,5- bis(aminomethyl)-2-isopropyl-1,3-dioxolane]platinum(II) (SKI2053R, NSC D644591), were evaluated and compared with those of cisplatin (CDDP) and carboplatin (CBDCA) using murine tumors. SKI 2053R was highly active in vitro against both L1210 murine leukemia and its CDDP-resistant subline, L1210/DDP; the relative resistances were 20.0-, 14.5-, and 2.7-fold for CDDP, CBDCA, and SKI 2053R, respectively. SKI 2053R showed activity comparable with or superior to either CDDP or CBDCA in mice implanted with L1210. In mice implanted with L1210/DDP, as compared with CBDCA, SKI 2053R showed high values for the percentage of treated survivors relative to controls and for numbers of cured mice, whereas CDDP had virtually no activity. In mice implanted with P388, all three drugs were highly active, but the intensity of activity was shown to be ranked in the following order: SKI 2053R > CDDP > CBDCA. The antitumor activity of SKI 2053R against Lewis lung carcinoma was comparable with that of both CDDP and CBDCA. The antitumor activity of SKI 2053R was further investigated against two human tumor xenografts, KATO III (stomach adenocarcinoma) and WiDr (colon adenocarcinoma), implanted s.c. in nude mice and was compared with that of CDDP. In SKI 2053R-treated groups, the time required for a mean tumor weight of 1,000 mg was 33.1 days in KATO III xenografts and 35.0 days in WiDr xenografts as compared with 30.2 and 27.2 days in CDDP-treated groups, respectively. SKI 2053R achieved growth-inhibition rates comparable with those of CDDP against KATO III (65% versus 59%) and WiDr xenografts (64% versus 54%) on day 35. These results indicate that SKI 2053R is an attractive candidate for further development as a clinically useful anticancer drug. [ABSTRACT FROM AUTHOR]

Although penicillin tolerance has been increasingly recognized among clinical isolates of many Gram-positive organisms, the significance of this phenomenon in vivo is not clear. The present study was performed to characterize penicillin-tolerant enterococci by several in-vitro parameters and to examine the significance in vivo in a rabbit model of infective endocarditis. Tolerant enterococci exhibited several characteristics which distinguished them from non-tolerant bacteria: significantly greater ratios of MIC to MBC of penicillin, resistance to penicillin-induced lysis and killing, and growth in areas of superinhibitory concentrations of penicillin upon transfer from penicillin gradient to penicillin-free plates. In-vivo studies of aortic valve endocarditis in rabbits treated with procaine penicillin G (300 mg/kg/day) revealed strikingly different responses between infections due to one tolerant and one non-tolerant strain. Animals infected with a tolerant enterococcus showed consistently greater bacterial counts in vegetations during ten days of therapy and significantly lower rates of vegetation sterilization. Serum penicillin levels were not significantly different between the two groups, but serum bactericidal titres were significantly lower for the tolerant than for the non-tolerant strains. These findings indicate that penicillin tolerance identified by several in-vitro criteria is a significant determinant of the in-vivo response of enterococci to penicillin therapy.

Intravenous immunoglobulins are stable monomeric pooled human IgG preparations for therapeutic use. Three intravenous immunoglobulins licensed in the United States are generally therapeutically equivalent. Intravenous immunoglobulin is the preferred agent for replacement therapy for most patients with primary or secondary antibody immunodeficiency because of the rapidity and ease of giving large quantities of IgG, even by self-administration. Disadvantages of intravenous immunoglobulins include frequent (approximately 10%) but usually not serious side effects, the need for venous access (often difficult in infants and young children), and high cost. Intravenous immunoglobulins are also beneficial in the prevention of certain viral infections, such as cytomegalovirus pneumonia and varicella; they may also have a synergistic effect with antibiotics in certain bacterial diseases. Intravenous immunoglobulin has also been used successfully in the management of idiopathic thrombocytopenia purpura, Kawasaki disease, and certain autoimmune diseases. Intravenous immunoglobulin may also be of use in certain high-risk and premature newborns. [ABSTRACT FROM AUTHOR]

One hundred and forty one patients were treated in a combined Eastern Cooperative Oncology Group and Southwest Oncology Group phase-III study evaluating low-dose cytarabine (LDAC) versus supportive therapy for the treatment of myelodysplastic syndrome (MDS). Patients were randomized to either cytarabine 10 mg/m2 subcutaneously BID or supportive therapy. Central pathology review was required. All patients were classified according to the FAB criteria for MDS. The overall concordance rate for the MDS subtype was 52%, and 25 patients were pathology exclusions, including 20 with AML. The overall response rate to a single cycle of LDAC was 32%, with 11% complete and 21% partial responses. The median duration of response was 5.9 months, with a range of 1.4-33.5 months. Responses were seen in all subtypes. Infections were more common in the LDAC arm. There was no difference in the time to progression or the overall survival for patients treated with LDAC or supportive therapy. The incidence of leukemic transformation was similar in both arms at 15%, but it differed according to the MDS subtype. Patients receiving LDAC had a decreased transfusion requirement after 3 months. There was a significant correlation between the degree of cytoreduction after receiving a single cycle of LDAC and survival. This survival difference was most marked in patients with the RAEB and RAEB-T subtypes. Although LDAC produced responses in all subtypes of the MDS, there was no effect on overall survival or transformation to AML. However, selected patients benefited from a single cycle of LDAC with durable responses. A cytoreductive effect appears to be required for a durable response. Future studies should include pathology review and must address the clinical and biological heterogeneity of MDS. [ABSTRACT FROM AUTHOR]

No clinical studies on the lipolytic effect of guanine nucleotide-binding protein β3 subunit gene ( GNB3) 825T polymorphism have been performed. This study was a subinvestigation of a 12-week randomized controlled trial ( NCT01184560) for the additive effect of orlistat on sibutramine treatment. The analysis involved 101 obese females aged 18-49 years, genotyped at the GNB3 825 locus. To exclude any influence from potential confounders, we used an analysis of covariance model. After the intervention, fat mass proportion in total weight loss was significantly lower in subjects with a T allele than in those without a T allele (p = 0.034). GNB3 825T allele was associated with blunted fat mass reduction in obese females. [ABSTRACT FROM AUTHOR]

Purpose To investigate the safety and a half-life of intravitreal povidone-iodine ( PVI) and the efficacy of single and repeat PVI injection in experimental S. epidermidis endophthalmitis. Methods In Phase I study, the pharmacokinetics and the safety of PVI were investigated. Forty New Zealand White rabbits receiving intravitreal 0.1% and 0.3% PVI were divided into Group I and II. The pharmacokinetics of PVI was analyzed using high performance liquid chromatography ( HPLC). To confirm the safety of intravitreal PVI, electroretinography ( ERG) and histologic examination were conducted at baseline, 6 and 12 hours. In Phase II study, the efficacy of PVI for the treatment of S. epidermidis endophthalmitis was evaluated in 4 groups (n = 10 in each group). After the induction of S. epidermidis endophthalmitis, 0.1% and 0.3% PVI were injected once in Group A and B, and three times every second day in Group C and D respectively. The fellow eyes receiving sham injection were the control. ERG, histologic examination and vitreous culture for S. epidermidis were conducted at day 14. Results In Phase I, 0.1% and 0.3% PVI groups did not show notable retinal damage in ERG and histologic findings and half-life in vitro was 3.27 and 3.58 hours, respectively. In Phase II, all Groups showed a significant improvement of endophthalmitis, compared to the controls. However, four eyes in Group A and 3 eyes in Group B demonstrated a bacterial growth in vitreous at day 14, but none in Group C and D. In the histologic findings, retinal damage was detected as lymphocyte infiltration in the inner retinal layers of eyes with bacterial growth. Conclusions 0.1% and 0.3% PVI can be tolerated in rabbit eyes. Half-life of the PVI was about 3 hours in vitreous. Repeat PVI injection with low concentration is likely to be effective and safe for the treatment of S. epidermidis endophthalmitis. [ABSTRACT FROM AUTHOR]

Background/aims: Peripheral blood stem cells (PBSC) are one of the most promising stem cell sources for treatment of ischaemic heart disease. However, the experience of mobilisation and collection of PBSC using granulocyte-colony stimulating factor (G-CSF) in patients with myocardial infarction (MI) is still limited. We report our experiences with the feasibility and safety of collection of mobilised PBSC with G-CSF in MI patients, and the influence of acute ischaemia on efficacy of PBSC collection. Methods: 74 patients with acute or old myocardial infarction (AMI vs OMI, n = 46 and n = 28) underwent PBSC collection after administration of G-CSF twice a day at a dose of 5 μg/kg for 3 days. Flow cytometric analysis of cell surface markers was performed. Results: No evidence of inflammation or ischaemia was observed during G-CSF mobilisation and PBSC collection. The yield of CD34
+ cells was 12.9 (SD 15.92) ×109 /l (5.04% (5.30%) of total cells) with a product volume of 37.9 (8.4) ml after 5650 (987) ml of blood were processed during PBSC collection. Stem cell mobilisation and collection by G-CSF is more efficient in AMI than in OMI, and proportions of cells positive for VE-cadherin or KDR/CD34 are significantly greater in AMI than in OMI (p<0.01). Conclusion: We could obtain sufficient numbers of PBSC for intracoronary infusion with the G-CSF-based mobilisation strategy without complications even in patients with MI. PBSC collection after mobilisation with G-CSF is a safe and feasible method of stem cell collection for therapeutic purpose in patients with MI. [ABSTRACT FROM AUTHOR]- Published
