Certain Risk Factors (certain + risk_factor)
Selected AbstractsEarly Surgical Morbidity and Mortality in Adults with Congenital Heart Disease: The University of Michigan ExperienceCONGENITAL HEART DISEASE, Issue 2 2008Ginnie L. Abarbanell MD ABSTRACT Objectives., To review early surgical outcomes in a contemporary series of adults with congenital heart disease (CHD) undergoing cardiac operations at the University of Michigan, and to investigate possible preoperative and intraoperative risk factors for morbidity and mortality. Methods., A retrospective medical record review was performed for all patients ,18 years of age who underwent open heart operations by a pediatric cardiothoracic surgeon at the University of Michigan Congenital Heart Center between January 1, 1998 and December 31, 2004. Records from a cohort of pediatric patients ages 1,17 years were matched to a subset of the adult patients by surgical procedure and date of operation. Results., In total, 243 cardiac surgical operations were performed in 234 adult patients with CHD. Overall mortality was 4.7% (11/234). The incidence of major postoperative complications was 10% (23/234) with a 19% (45/23) minor complication rate. The most common postoperative complication was atrial arrhythmias in 10.8% (25/234). The presence of preoperative lung or liver disease, prolonged cardiopulmonary bypass and aortic cross clamp times, and postoperative elevated inotropic score and serum lactates were significant predictors of mortality in adults. There was no difference between the adult and pediatric cohorts in terms of mortality and morbidity. Conclusions., The postoperative course in adults following surgery for CHD is generally uncomplicated and early survival should be expected. Certain risk factors for increased mortality in this patient population may include preoperative presence of chronic lung or liver dysfunction, prolonged cardiopulmonary bypass and aortic cross-clamp times, and postoperative elevated inotropic score and serum lactate levels. [source] Risk Factors in Sudden Death in Epilepsy (SUDEP): The Quest for MechanismsEPILEPSIA, Issue 5 2007Lina Nashef Summary:, People with epilepsy may die suddenly and unexpectedly without a structural pathological cause. Most SUDEP cases are likely to be related to seizures. SUDEP incidence varies and is <1:1,000 person-years among prevalent cases in the community and ,1:250 person years in specialist centres. Case,control studies identified certain risk factors, some potentially amenable to manipulation, including uncontrolled convulsive seizures and factors relating to treatment and supervision. Both respiratory and cardiac mechanisms are important. The apparent protective effect of lay supervision supports an important role for respiratory factors, in part amenable to intervention by simple measures. Whereas malignant tachyarrhythmias are rare during seizures, sinus bradycardia/arrest, although infrequent, is well documented. Both types of arrhythmias can have a genetic basis. This article reviews SUDEP and explores the potential of coexisting liability to cardiac arrhythmias as a contributory factor, while acknowledging that at present, bridging evidence between cardiac inherited gene determinants and SUDEP is lacking. [source] Talcum powder, chronic pelvic inflammation and NSAIDs in relation to risk of epithelial ovarian cancerINTERNATIONAL JOURNAL OF CANCER, Issue 1 2008Melissa A. Merritt Abstract Chronic inflammation has been proposed as the possible causal mechanism that explains the observed association between certain risk factors, such as the use of talcum powder (talc) in the pelvic region and epithelial ovarian cancer. To address this issue we evaluated the potential role of chronic local ovarian inflammation in the development of the major subtypes of epithelial ovarian cancer. Factors potentially linked to ovarian inflammation were examined in an Australia-wide case,control study comprising 1,576 women with invasive and low malignant potential (LMP) ovarian tumours and 1,509 population-based controls. We confirmed a statistically significant increase in ovarian cancer risk associated with use of talc in the pelvic region (adjusted odds ratio 1.17, 95% CI: 1.01,1.36) that was strongest for the serous and endometrioid subtypes although the latter was not statistically significant (adjusted odds ratios 1.21, 95% CI 1.03,1.44 and 1.18, 95% CI 0.81,1.70, respectively). Other factors potentially associated with ovarian inflammation (pelvic inflammatory disease, human papilloma virus infection and mumps) were not associated with risk but, like others, we found an increased risk of endometrioid and clear cell ovarian cancer only among women with a history of endometriosis. Regular use of aspirin and other nonsteroidal anti-inflammatory drugs was inversely associated with risk of LMP mucinous ovarian tumours only. We conclude that on balance chronic inflammation does not play a major role in the development of ovarian cancer. © 2007 Wiley-Liss, Inc. [source] Personal and non-occupational risk factors and occupational injury/illnessAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 4 2006Brian N. Craig PhD Abstract Background The materials handling industry performs is an essential function in the world economy, however, it is plagued with occupationally related injuries and illnesses. Understanding the risk factors may assist this industry in alleviating these injuries and illnesses, as well as their associated costs. Methods Forty-eight personal and non-occupational risk factors were measured and evaluated for statistically significant relationships with occupational injury in 442 volunteer manual material handlers who worked for three different companies, at nine US locations, with 15 different job descriptions. OSHA 200 logs were used to ascertain evidence of occupational injury within this population for 1 year after the testing and measurement was completed. Results Higher occurrences of injury were significantly associated with six risk factors in the univariate model (odds ratios 1.51,4.00). The significantly (P,<,0.05) related risk factors in the univariate model were aerobic power, smoking status, perceived fitness level, fishing/hunting as a hobby, speed limit obeyance, and witnessing or being involved in a violent fight. In the multivariate analysis, five risk factors (aerobic power, smoking status, percent body fat, body mass index, and sit-and-reach measured flexibility) were significantly (P,<,0.05) associated with occupational injury. Odds ratios in the multivariate analysis varied from 1.42 to 10.11. Conclusion Evidence of an association of occupational injury occurrence with certain risk factors presented in personal and non-occupational univariate and multivariate models is shown. In industry, effective injury reduction programs should go beyond traditional methods of job-related ergonomic risk factors and include personal factors such as smoking, weight control, and alcohol abuse.

Hamilton Two concerns expressed by the American Society of Transplant Surgeons (ASTS) are that (1) the new Medicare regulations for transplant hospitals take a ,punitive' approach and that (2) the outcome requirement may thwart innovation by not including certain risk factors into the risk adjustment used to calculate expected outcomes. This article explains efforts by the Centers for Medicare & Medicaid Services (CMS) to encourage quality improvement. CMS limits outcomes-related enforcement to situations where failure rates exceed certain substantial ,tolerance limits', ensuring opportunity for quality improvement to be effective prior to enforcement. Transplantations involving a disproportionate share of risk factors not incorporated into the risk-adjustment methodology can also be raised through CMS',mitigating factors' process. Of the 22 mitigating factor requests completed through March 10, 2009, 7 raised issues of risk adjustment (none involved experimental protocols). Four of the seven requests were approved for other reasons (evidence of effective program changes and improved outcomes). CMS concluded that none of the seven made a persuasive case based on risk factors. The early data indicate that program deficiencies may outweigh risk adjustment issues. CMS agrees to consider the ASTS suggestions for future action and continues to monitor the situation in case a different pattern emerges. [source] | ||||||||||
