An unusual case of epigastric heteropagus: parasite with a rudimentary heart

Parasitic or heterotopic conjoined twins are exceedingly rare, and these cases are referred to as "heteropagus" when there is a parasitic attachment in a nonduplicated fashion to any portion of the body. Epigastric heteropagus twinning refers to the attachment of the parasite to the epigastric region of the autosite. An unusual epigastric heteropagus case is presented with a rudimentary cardiopulmonary and also nearly complete gastrointestinal and genitourinary system of the parasite, and an organogenetic and vascular status of the previously reported cases are reviewed. The current case might be unique for the parasite having a cardiopulmonary development--although rudimentary--and this might be the reason that it has more complete organogenesis than the cases that have been presented previously in the literature.     

Orem自理模式应用于产程管理中的效果探讨

目的:探讨Qrom自理模式在产程管理中的可行性和效果。方法:选择同期拟经阴道分娩产妇200例,其中100例实施常规产时服务模式管理(对照组),100例实施自理模式管理(自理组),比较两组产妇的分娩结局、产时干预情况、产妇满意度和助产士满意度。结果:自理组无指征剖宫产率、椎管内麻醉镇痛率、全程导乐陪伴率、催产素使用率明显低于对照组,产妇满意度和助产士满意度高于对照组。两组上述各项指标比较,差异有显著性或极显著性意义(P<0.05或P<0.01)。结论:O rem自理模式应用于产程管理中可促进自然分娩,减少产时干预,提高产妇和助产士满意度。

Vascular endothelial growth factor expressing mesenchymal stem cells improves cardiac function in chronic myocardial infarction in pigs

Transplantation of mesenchymal stem cells （MSCs） for myocardial reconstruction has shown promise in both animal models and human phase 1 clinical studies. Vascular endothelial growth factor （VEGF） is a strong therapeutic agent for treating ischaemia by inducing angiogenesis. The feasibility of ex vivo MSCs mediated gene transfer is documented. Matsumoto and colleagues have recently reported genetically engineered MSCs carrying VEGF165 delivery for revascularization in a model of acute myocardial infarction （MI）. The promising data from our laboratory in both angiogenesis and MSCs transplantation in cunicular heart model of acute MI have prompted us to attempt the combined and simultaneous application of the two strategies.

Risk factors for early-onset, ventilator-associated pneumonia in critical care patients: selected multiresistant versus nonresistant bacteria

BACKGROUND: Ventilator-associated pneumonia is the leading nosocomial infection in critically ill patients. The frequency of ventilator-associated pneumonia caused by multidrug-resistant bacteria has increased in recent years, and these pathogens cause most of the deaths attributable to pneumonia. The authors, therefore, evaluated factors associated with selected multidrug-resistant ventilator-associated pneumonia in critical care patients. METHODS: The authors prospectively recorded potential risk factors at the time of intensive care unit admission. An endotracheal aspirate was obtained in all patients who met clinical criteria for pneumonia. Patients were considered to have ventilator-associated pneumonia only when they met the clinical criteria and aspirate culture was positive for bacteria 48 h or more after initiation of mechanical ventilation. Pediatric patients were excluded. Adult patients with ventilator-associated pneumonia were first grouped as "early-onset" (< 5 days) and "late-onset," determined by episodes of ventilator-associated pneumonia, and then, assigned to four groups based on the bacteria cultured from their tracheal aspirates: Pseudomonas aeruginosa, Acinetobacter baumanii, methicillin-resistant staphylococci, and all others. The first three bacteria were considered to be multidrug resistant, whereas the others were considered to be antibiotic susceptible. Potential risk factors were evaluated with use of univariate statistics and multivariate regression. RESULTS: Among 486 consecutive patients admitted during the study, 260 adults underwent mechanical ventilation for more than 48 h. Eighty-one patients (31%) experienced 99 episodes of ventilator-associated pneumonia, including Pseudomonas(33 episodes), methicillin-resistant staphylococci (17 episodes), Acinetobacter(9 episodes), and nonresistant bacteria (40 episodes). Sixty-six of these episodes were early onset and 33 episodes were late onset. Logistic regression analysis identified three factors significantly associated with early-onset ventilator-associated pneumonia caused by any one of the multidrug-resistant bacterial strains: emergency intubation (odds ratio, 6.4; 95% confidence interval, 2.0-20.2), aspiration (odds ratio, 12.7; 95% confidence interval, 2.4-64.6), and Glasgow coma score of 9 or less (odds ratio, 3.9; 95% confidence interval, 1.3-11.3). A. baumanii-related pneumonia cases were found to be significantly associated with two of these factors: aspiration (odds ratio, 14.2; 95% confidence interval, 1.5-133.8) and Glasgow coma score (odds ratio, 6.0; 95% confidence interval, 1.1-32.6). CONCLUSIONS: The authors recommend that patients undergoing emergency intubation or aspiration or who have a Glasgow coma score of 9 or less be monitored especially closely for early-onset multidrug-resistant pneumonia. The occurrence of aspiration and a Glasgow coma score of 9 or less are especially associated with pneumonia caused by A. baumanii.
