To examined the prevalence of hip and knee arthroplasty in patients with inflammatory bowel disease (IBd) by comparing the diagnostic codes for these procedures in patients with IBd and a control group of patients. METHOdSThe National Inpatient Sample database (NIS) is part of the Healthcare Cost and Utilization Project (HCUP), the largest publicly available inpatient healthcare database in the United States. The NIS samples about 20% of discharges from all community hospitals participating in HCUP, representative of more than 95% of the United States population, with approximately 7000000 hospitalizations reported annually. NIS contains data on diagnoses, procedures, demographics, length of stay (LOS), co-morbidities and outcomes. ICd-9-CM diagnostic codes for primary hospitalizations for arthroplasty of the hip or knee with a co-diagnosis of IBd [combining both Crohn’s disease (Cd) and ulcerative colitis (UC)] were used to identify study subjects for cost and LOS analysis for NIS from 1999-2012. Statistical analysis: 1: 2 propensity score matching between IBd vs a control group based on following factors: Patient age, gender, race, total co-morbidities, # of procedures, admission type, insurance, income quartiles, and hospital bed size, location and hospital teaching status. Categorical variables were reported as frequency and compared by χ2 tests or fisher’s exact tests. Individual 1:3 matching was also performed for patients carrying diagnostic codes for Cd and for patients with the diagnostic code for UC. After matching, continuous variables were rcompared with Wilcoxon signed rank or Paired T-tests. Binary outcomes were compared with the McNemar’s test. This process was performed for the diagnosis of hip or knee arthroplasty and IBd (Cd and UC combined). Prevalence of the primary or secondary diagnostic codes for these procedures in patients with IBd was determined from NIS 2007. rESULTSCosts and mortality were similar for patients with IBd and cont

This paper presents the preclinical evaluation of a novel immobilization system for patients undergoing external beam radiation treatment of head and neck tumors. An immobilization mask is manufactured directly from a 3-d model, built using the CT data routinely acquired for treatment planning so there is no need to take plaster of Paris moulds. research suggests that many patients find the mould room visit distressing and so rapid prototyping could potentially improve the overall patient experience. Evaluation of a computer model of the immobilization system using an anthropomorphic phantom shows that >99% of vertices are within a tolerance of ±0.2 mm. Hausdorff distance was used to analyze CT slices obtained by rescanning the phantom with a printed mask in position. These results show that for >80% of the slices the median “worse-case” tolerance is approximately 4 mm. These measurements suggest that printed masks can achieve similar levels of immobilization to those of systems currently in clinical use.

本文报导了一个新发现的H置换Ni(100)面上化学吸附CO的表面反应.CO分子在Ni(100)面上的化学吸附(吸附热为126J/mole)比氢的原子吸附(吸附热为96kJ/mole)强得多,在通常条件下,H不能置换Ni(100)面上化学吸附的CO.但是当H压高于1×10乇时,在温度为270～330K的范围内可引起H置换化学吸附CO的表面反应.本文用荧光产率近边吸收谱(FYNES)和程序升温脱附(TPd)对H置换化学吸附CO的表面反应动力学进行了详细的研究.FYNES谱在原理上与NEXAFS相同,通过测量含碳受激分子在弛豫过程中释放的碳—Kα荧光产率代替测量Auger电子产率,所以可在有气氛压力下对表面反应动力学过程进行原位考察.实验结果表明,在氢压为10至10乇和单晶温度为270至330K范围内,置换反应的速度公式可表示为:-dθ/dt=kθP式中θ为CO的表面覆盖度,P为气相氢压.置换反应是一个热活化过程,它随CO覆盖度的降低显示出二个不同的动力学区域,置换反应的活化能在高覆盖度下为29±4kJ/mole,在低覆盖度下为46±4kJ/mole.这比CO在Ni(100)面上的吸附热105～126kJ/mole约低75～80J/mole.本文对置换反应的控制步骤和H置换的机理进行了讨论

To improve follow-up with primary care providers after acute Emergency depart ment (Ed) asthma visits for children from low-income urban families. A prospect ive, randomized, controlled trial evaluated combined telephone asthma coaching a nd monetary incentive. The primary outcome was asthmaplanning visits with primar y care providers within 15 days of index Ed visits. The subjects were urban pare nts whose children were treated for asthma in the Ed and had Medicaid or no insu rance. We enrolled 527 parents (264 control and 263 intervention). There was a significant differ ence (P rvention (35.7%) and control (18.9%) grou ps in the proportion of children who had asthma-planning visits and decreased m ean nights/days with asthma symptoms by 4.36 intervention and 3.31 control at 2 weeks. The proportions of children with asthma-planning visits and acute asth ma care visits during the 16-day to 6-month period were similar for both group s. Telephone coaching and a monetary incentive significantly increased the propo rtion of low-income urban parents who brought their children for asthma-planni ng visits, and decreased asthma symptoms shortly after asthma Ed visits. The int ervention did not increase subsequent asthma-planning visits or decrease Ed vis its or hospitalizations.
