In the United States, when medical devices are associated with adverse events that result in death or serious injury, or have malfunctions that could lead to death/serious injury, these events must be reported to the Food and Drug Administration’s Center for Devices and Radiologic Health by device manufacturers and user facilities. However, the defects in the medical device evaluation process (...

BACKGROUND Most cases of Type 2 diabetes are attributable to excess weight and physical inactivity. We investigated trends in mortality based on doctors' certification of diabetes and obesity. METHODS Analysis of a national data set of all certified causes of death, i.e. underlying cause and contributing causes ('mentions'), in England 1995-2010. RESULTS Diabetes exhibited divergent trends ...

OBJECTIVE To analyze diabetes mellitus-related mortality among elderly and the rate of undereporting of diabetes mellitus as a cause of death when statistical data on diabetes exclusively on the underlying cause of death are considered. METHODS A total of 2.974 death certificates of elderly people living in a housing project in the city of Rio de Janeiro were revised. The study period was 199...

results 111 female and 142 male were available from a total of 253 confirmed h1n1 cases. the minimum and maximum ages were 1.5 and 90 years, respectively. the most common symptoms were fever and cough. 144 cases had record of hospitalization, 100 cases were undergone outpatient treatment and nine cases have not recorded the treatment status. the most frequent underlying manifestation was hypert...

An integrated manufacturing process simulation framework has been developed to predict the trimmed edge tensile stretchability of AA6111-T4 sheets by incorporating the burr geometry, damage, and plastic strain from trimming simulations into subsequent tensile stretchability simulations. The influence of the trimming die clearances on the predicted tensile stretching ductility (stretchability) i...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited. Abstract This note describes some theoretically-possible failure modes for TCP connections and discusses possible remedies. In particular, one very simple fix is identified.

purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

MEMS components by their very nature have different and unique failure mechanisms than their macroscopic counterparts. This paper discusses failure mechanisms observed in various MEMS components and technologies. MEMS devices fabricated using bulk and surface micromachining process technologies are emphasized.
