Impact of aprotinin and renal function on mortality: a retrospective single center analysis
<p>Abstract</p> <p>Background</p> <p>An estimated up to 7% of high-risk cardiac surgery patients return to the operating room for bleeding. Aprotinin was used extensively as an antifibrinolytic agent in cardiac surgery patients for over 15 years and it showed efficacy in reducing bleeding. Aprotinin was removed from the market by the U.S. Food and Drug Administration after a large prospective, randomized clinical trial documented an increased mortality risk associated with the drug. Further debate arose when a meta-analysis of 211 randomized controlled trials showed no risk of renal failure or death associated with aprotinin. However, only patients with normal kidney function have been studied.</p> <p>Methods</p> <p>In this study, we look at a single center clinical trial using patients with varying degrees of baseline kidney function to answer the question: Does aprotinin increase odds of death given varying levels of preoperative kidney dysfunction?</p> <p>Results</p> <p>Based on our model, aprotinin use was associated with a 3.8-fold increase in odds of death one year later compared to no aprotinin use with p-value = 0.0018, regardless of level of preoperative kidney dysfunction after adjusting for other perioperative variables.</p> <p>Conclusions</p> <p>Lessons learned from our experience using aprotinin in the perioperative setting as an antifibrinolytic during open cardiac surgery should guide us in testing future antifibrinolytic drugs for not only efficacy of preventing bleeding, but for overall safety to the whole organism using long-term clinical outcome studies, including those with varying degree of baseline kidney function.</p
Global, regional, and national cancer incidence, mortality, years of life lost, years lived with disability, and disability-Adjusted life-years for 29 cancer groups, 1990 to 2017 : A systematic analysis for the global burden of disease study
Importance: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data. Objective: To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning. Evidence Review: We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-Adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence. Findings: In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572000 deaths and 15.2 million DALYs), and stomach cancer (542000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601000 deaths and 17.4 million DALYs), TBL cancer (596000 deaths and 12.6 million DALYs), and colorectal cancer (414000 deaths and 8.3 million DALYs). Conclusions and Relevance: The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care. © 2019 American Medical Association.

Auditory and Respiratory Health Disorders Among Workers in an Iron and Steel Factory
Background: Iron is the world's most commonly used metal and can usually be found with other elements in the form of steel. The frequently recorded health disorders between iron and steel industry workers includes: respiratory and skin problems as
well as noise-related hearing impairment.
Objectives: Study auditory and respiratory health disorders among exposed workers in an iron and steel factory in Sadat city, Menoufiya governorate and assess workplace environment in the same factory.
Participants and Methods: One hundred and six occupationally exposed male workers in an iron and steel factory was chosen and matched for age, sex, residence, education, income and smoking habit with a control (non exposed) group. A predesigned
questionnaire including personal and occupational data and some respiratory and auditory manifestations was filled. All participants were subjected to spirometric measurements and audiometry. Environmental study for noise, dust and fumes
measurements was also done.
Results: Environmental study revealed higher mean value of noise and lower mean values of dust and fumes than the standard levels. Exposed workers showed significant higher prevalence of respiratory and auditory manifestations, spirometric and auditory findings than controls. With increasing years of employment, deterioration of spirometric measurements and audiometric changes increase.
Conclusion: From environmental measures, although dust and fume levels were lower than the PEL; there were early changes in the spirometric measurements in exposed workers. Working in iron and steel industry may be associated with higher
prevalence of chest manifestations, hearing impairment, changes in the mean values of different spirometric measurements and noise induced hearing loss.
Recommendations: Exclusion of individuals having any respiratory or auditory manifestations during pre-employment medical examination. For early detection of respiratory and auditory disorders, spirometry and audiometry should be included in the periodic medical examination. Accurate health records of workers, so, those at risk can be monitored, and/or pre-placed. Using personal protective equipments
especially masks and ear muffles as well as prohibit smoking in the workplace.
