AIm To determine morbidity and mortality in this specific patient group and also to assess for any independent associations between Do Not Resuscitate(DNR) status and increased post-operative morbidity and *** We conducted a propensity score matched retrospective analysis using de-identified data from the American College of Surgeons' National Surgical Quality Improvement Project(ACS NSQIP) for all patients undergoing hip fracture surgery over a 7 year period in hospitals across the United States enrolled in ACS NSQIP with and without Do Not Resuscitate Status. We measured patient demographics including DNR status, co-morbidities, frailty and functional baseline, surgical and anaestheticprocedure data, post-operative morbidity/complications, length of stay, discharge destination and *** Of 9218 patients meeting the inclusion criteria, 13.6% had a DNR status, 86.4% did not. mortality was higher in the DNR status compared to the non-DNR group, at 15.3% vs 8.1% and propensity score matched multivariable analysis demonstrated that DNR status was independently associated with mortality(OR = 2.04, 95%CI: 1.46-2.86, P matched cohort demonstrated that DNR status was associated with a significant, but very small increased likelihood of post-operative complications(0.53 vs 0.43 complications per episode; OR = 1.21; 95%CI: 1.04-1.41, P = 0.004). Cardiopulmonary resuscitation and unplanned reintubation were significantly less likely in patients with DNR *** Whilst DNR status patients had higher rates of postoperative complications and mortality, DNR status itself was not otherwise associated with increased morbidity. DNR status appears to increase 30-d mortality via ceilings of care in keeping with a DNR status, including withholding reintubation and cardiopulmonary resuscitation.

International Journal of Clinical medicine 2013年第7期4卷 18-23页

作者： Rawan m. bader Guangtai Song Eyad Y. Almuhtaseb Department of Orthodontic Dentistry of medical College of Huazhong University of Science and Technology Wuhan China. Department of Pediatric Dentistry of School and Hospital of Stomatology Wuhan University Wuhan China Department of Pediatric Dentistry of School and Hospital of Stomatology Wuhan University Wuhan China ministry of Higher Education Putrajaya Kingdom of Saudi Arabia

Dental care under general anesthesia (DGA) was found to be a safe, efficient and effective quality treatment for children. Purpose: To describe the characteristics of child dental patients treated under DGA and describe the indications of the treatments and types of treatments provided. method: The sample consisted of 40 patients treated under DGA at Department of Paediatric Dentistry of school and Hospital of Stomatology of Wuhan University between June 2011 and December 2012. Detailed information was collected from dental records. SPSS software package was used for statistical analysis. Results: The age of the patients ranged from 2.5 years to 24.1 years. males were more common than females m:F 1.5:1 .The mental retardation patients accounted for (5%) of the sample. The most common indication was inability to cooperate and accept dental treatment under local anesthesia (95%). The treatments rendered included: caries restorations (37%), root canal treatments (34%), extractions (7%), fluoride application (6%), fissure sealants (6%), indirect pulp capping (5%), stainless steel crowns (4%), pulpotomies (0.8%) and labial frenectomy (0.1%). In the follow-up visit fillings were found to be lost in 3 patients, with 2 anterior teeth and one posterior tooth. Conclusion: Caries restoration and root canal treatments were the most common treatments provided. Preventive strategies should be targeted toward children to reduce the number of healthy children receiving treatment under general anesthesia. Clinical significance: This study provides baseline information regarding the types of treatments for paediatric dental patients inWuhanand it is hoped that the data from this study will be useful for other researchers.

Vulnerability Assessment Using Raster Calculation and DRASTIC model for the Jordan Valley Subsurface Basin (AB1) Imaging maps

Journal of Geographic Information System 2014年第6期6卷 585-593页

作者： Atallah m. Al-Shatnawi Rabah Al-Shboul bader m. Al-Fawwaz Wafa Al-Sharafat Refaat m. Bani Khalf Department of Information Systems Al-albayt University Mafraq Jordan Department of Computer Sciences Al-albayt University Mafraq Jordan Water Authority of Jordan Amman Jordan

The vulnerability to pollution of the area between Wadi Shueib and the Dead Sea in the Jordan Valley (AB1) subsurface basis was assessed and evaluated using raster calculation and DRASTIC model for imaging maps in this research. The seven DRASTIC model parameters are: Depth to water, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone and Hydraulic conductivity. The seven variables are evaluated by the rating and the weighting numerical indexes. The vulnerability parameters are categorized depending on a fixed interval of suburban area percentage. It showed that the ABI Subsurface was categorized by high vulnerability classes while the middle and western parts were categorized by high to extreme vulnerability classes. The southern part of the AB1 displayed low aquifer vulnerability. The vulnerability map shows the high risk suffered by the middle and western parts of the AB1 Subbasin due to the high possibility pollution of intensive fruit and vegetable cultivation.
