Use of Visualization Techniques to Augment Traditional Adverse Event Signal Detection

Traditional qualitative signal detection and evaluation is a process that needs to be carefully designed to ensure efficiency and reproducibility of analysis results. It is focused on deciphering a potential signal of a possible unexpected adverse reaction, or change in severity, characteristics or frequency of an unexpected event. Such a potential signal would normally be an emerging safety pattern that is embedded within a dataset.

Multiple data sources need to be screened for possible signals as part of post-market signal detection and evaluation process and may include spontaneous AEs/ADRs (including published literature sources), medical/insurance claims databases, drug usage, and Safety Registries (post-market) databases. For marketed drugs with ongoing clinical trials, data screened should also include post-market clinical trials safety data and epidemiological data where applicable.

For easier and faster review and signal screening of data, this process can include the use of a visualization application that may or may not be integrated with a validated safety database application from where the analysis datasets will be obtained. Also, trained Signaling Assessors and Medical Reviewers should be part of the core procedure with clearly defined roles and responsibilities, as well as integrated quality control and quality assurance procedures being critical aspects of the overall process.

Use of visualization methods is not meant to replace but augment and facilitate traditional qualitative review of Individual Case Safety Reports (ICSRs) and/or aggregate data.

Example of a Visualization Analysis: Demographics Trends Analysis:

Where data is available, visualization signal screening of spontaneous data should include review and analysis of the following parameters:

  • Serious adverse events (ICSRs and aggregate data)
  • Non-serious events (Aggregate data analysis)
  • Reporting frequency of events, especially ADRs that are, or may be, causally related to the use of the drug or biologics product
  • Dosage Analysis: Evaluation of the extent of exposure at relevant doses; this could be an estimated exposure rate for spontaneous events
  • Other Dosage Analysis: Dose, plasma level (if available), duration of exposure, etc.
  • Adverse event profile of vulnerable populations such as: pediatric, elderly, pregnant women, etc.
  • Adverse event profile of high-risk populations: for example, patients with impaired liver or kidney functions, consistent, spurious or intermittent spikes or abnormalities of hepatic tests or renal function tests, co-morbid illnesses, metabolic status and genetic characteristics, such as, genetic predispositions, etc.
  • Cardiac events and related events (also included as DMEs)
  • Drug-Drug interactions or potential interactions, other drug-related factors
  • Demographic analyses, e.g., age, gender, ethnicity, race, etc.
  • Concomitant medications burden
  • Comorbidity burden
  • Designated Medical Events (DMEs)
  • Rare events, that is, events that are less likely to occur in the absence of drug exposure

In a visualization analysis, the Signal Assessor/Medical Reviewer considers all of the findings of the traditional qualitative signal detection analysis including the following:

  • Demographic trends: AE/ADR distribution across demographic groups such as age, gender, disease indication sub-populations (geriatric age grouping, pediatric, women of child bearing age, pregnancy, organ-impaired patients-decreased hepatic and renal function, etc.)
  • Polypharmacy: The confounding effect (impact) of one or more concomitant medications
  • Concurrent/Inter-current Illnesses: Underlying diseases that may predispose patients to developing DMEs, TMEs or other events
  • Rarity of AE/ADR: Some events are rare in the disease indication population or even in the natural population in absence of drug exposure, e.g., Progressive multifocal leukoencephalopathy (PML)/Progressive Multifocal Leukoencephalitis
  • Race and genetics: Race and genetic polymorphisms (where data is available) should be considered; some hereditary factors known to affect bioavailability of drugs and which may contribute to the development of ADRs.
  • Impact of any medication errors and potential for medical errors
  • Impact of off-label use (including off-label pediatric use) and potential for off label use.
  • Impact of any misuse/overdose and potential for misuse/overdose

Bulk of the Production is gradually approaching the market price of the practical, to the user an acceptable level. by mass of different industries, the use of the test of time. many successful cases to appreciate the ceramic bearing and ceramic ball bearings caused by maintenance-free, long life , high stability, low-cost advantage. ceramic bearing and ceramic ball from the research stage to mass production trial stage, the wave of large-scale applications have been coming.

3. The Development of Foreign Ceramic Bearing and Ceramic Ball Bearings
Since 1972 the birth of the first set of ceramic bearings in the United States (NASA) NASA,successfully developed the first set of ceramic bearings, the world has been scrambling to develop a new generation high performance ceramic bearings, pick up after nearly four years to the most prominent effect of ceramic bearings is greatly improved over the life of the bearing and the speed limit for the development of high-speed and ultra high speed, high precision machine tools provide the basis for parts. In addition, high temperature, corrosion, insulation, vacuum, chemical and other industry applications has achieved good results. Leading bearing company in the world today are all in the development, production of ceramic bearing and ceramic ball bearings, while the level of product quality has become a measure of the strength of their business is an important sign. According to incomplete statistics, up to now, foreign to the production of ceramic bearings: the United States, Japan, Germany, France, Russia, South Korea, the United Kingdom and other countries. The ceramic ball bearings early start of production in foreign countries, the use of a wide range of occasions, such as CNC machine tools with ceramic ball bearings, grinding spindle with ceramic ball bearings, machine tool ball screws with ceramic ball bearings. The high wear resistance of ceramic ball bearings, self-lubricating, high speed and other performance has been brought into fuller play, but also for high-precision machine tools, high-speed machine tools, special equipment to make a contribution to the environment. As a core component of ceramic ball bearings ceramic ball — and foreign R & D and competition more intense. Norton United States production of the adoption of HIP ceramic ball at the international level on the world-class event. Countries of the world’s leading ceramic ball bearings in a major Swedish company SKF, German FAG, Saint-Gobain of France, Japan, NSK, KOYO, NMB (U.S. Praia) and so on.

4. The Development of the Domestic Ceramic Bearing and Ceramic Ball Bearings

4.1ceramic bearings in China started relatively late, the domestic research and development of ceramic bearing and ceramic ball bearings in the university, the hospital all: Shanghai Institute of Ceramics, Shanghai, materials, pottery, Shandong Engineering Institute, Guangdong University of Technology, Tianjin University, Los axis and so on. Domestic manufacturers of ceramic bearings are mainly located in Beijing, Shanghai, and Zhejiang. Los axis made a number of the Shanghai Silicate samples, have not seen the industrial enterprises. Compared with foreign countries, the development of ceramic bearing situation is not optimistic. To the formation of the domestic industrial scale production of ceramic bearing almost no business. Be traced, of course, many factors, such as technology, personnel, funds, especially market unable to feel a lack of confidence. The current domestic ceramic bearing and ceramic ball bearings in research and development work, in general there are problems there are several seriously hampered China’s ceramic bearing and ceramic ball bearings development.

4.2the domestic ceramic bearing and ceramic ball bearing problems in research and development

4.2.1 we have seen reported are now high-speed, high-precision ceramic ball bearings in the research and development, and is often based mostly around the silicon nitride balls, the main problem, one is the system blank of ceramic balls, the other is high-precision ceramic ball method of processing technology, mostly in the use of high-speed machine tools, CNC machine tools, high-speed spindle occasions, long life and low noise requirements of the ceramic ball bearings, ball consistently failed to blank out SI3N4 manufacturing and processing of new materials such as: SiC, ZrO2, ZTA, Sialon and other materials is still a small amount of research, production and proved that the vast majority of manufacturers ZrO2 application. Causes concern because the cost of materials and processes can not be a good large-scale use. Haining Kang Knight Bearing Manufacturing Co., Ltd production of low noise, friction, anti-static ceramic ball bearings and Japan NMB’s the same size ceramic ball bearings for a detailed contrast, the difference in dB on 2 db, a good product can do 20db. and foreign products the same. But the price the company was positioned in about 15% of NMB. And domestic appliances can be directly supporting the motor. But this price is still higher than normal bearing a big slice, only the export of high-grade and can be used in household appliances.

4.2.2the ceramic bearing and ceramic ball bearings and bearing production is high-tech ceramics manufacturing technology combined with industry, both are very high degree of specialization, such as ceramics and bearing do not solve the problem of industrial combination, to achieve high-quality high-volume, low- cost of production, to meet the market demand is just empty talk. Today, the domestic manufacturing enterprises can not produce bearing ceramic material capable of producing ceramic materials not bearing manufacturing companies, professional and interdisciplinary serious gap in the practical application, the current number of bearing manufacturers of ceramic bearing and ceramic ball bearings in the professional knowledge In particular, ceramic materials science and engineering research is relatively small, people familiar with the ceramic bearing and ceramic ball bearings on the surface content. Resulting in a bearing is made of ceramic material is ceramic bearings, ceramic ball is added the situation of ceramic ball bearings. Domestic ceramic bearing and ceramic ball bearings can only be corrosion-resistant, never power, must magnetism, low speed, light load environment. There is the domestic manufacture of ceramic materials there is a big problem in customs clearance processes and technologies are not yet under the premise of the blind pursuit of material properties caused by low prices simply can not reach the expected results. Makes the ceramic bearing and ceramic ball bearings into the development of new wrong, also contributed to greater use of units of the ceramic bearing and ceramic ball bearings have lost confidence.

4.2.3as the high-tech product development, to go through technology-intensive and capital-intensive inputs into two stages, industrial production of ceramic bearings, it is necessary to overcome many technical difficulties, and the use of challenges and requires a large capital investment, but also market position to grasp the need to develop domestic industry insight and ceramic ball bearings ceramic bearing high standard of responsibility. Crudely bound to bring low-cost competition and the market deteriorate further. Primitive accumulation of capital and sustained re-investment must serve the ceramic bearing and ceramic ball bearings to the developments in the field of higher quality. At this stage of the development of ceramic bearing showed scattered, fragmented, small-scale production of a lack of overall awareness of local and macro-strategic thinking.

5. Look ceramic bearing and ceramic ball bearings with prospects
Ceramic bearing and ceramic ball bearings have many excellent properties such as: self-lubricating, high temperature, corrosion resistant, magnetic, electrical insulation, etc.. Yet in the wider field of development and utilization of potential, their applications are huge. The first high-quality and high-speed ceramic ball bearings do excellent services to the domestic machine tool industry. The high-speed, high precision spindle and spindle bearing own a large amount of the estimated annual demand, which picked up in a few million more. But the high-precision spindle bearings require relatively high quality than harsh, like the P4 level and above G5-bearing requirements of high-precision ceramic ball, now very few manufacturers are able to produce and the product stability is poor. Second: medium-quality ceramic bearings can be extensive and well used in many areas like oil exploration, oil refining, particular fine chemicals, chemical fiber, new energy, printing and dyeing, electroplating industry, waste water treatment, marine development, deep-water pumps, acid pumps, high temperature, vacuum, magnetic resonance, electrical insulation, medical, X-ray tube and the food industry, and more. On one hand, many only require the general accuracy class; medium and low speed and load; on the other hand, requirements are that they should resist a certain concentration of acid, alkali and salt corrosion; resistant to 300 ¯ 400 ℃ high temperature; not magnetic, electric, non-toxic; can be used without oil or self-lubrication of the working medium; in seawater can also be used. Bearing applications in these areas account for a very large proportion of special bearings, and ceramic bearing and ceramic ball bearings are fully capable to replace, even barely reach the metal bearing's work which may be competent and incompetent. On the whole, engineering ceramics has its irreplaceable position. Having such a huge market as the premise, our product development and manufacturing can create a new way and broaden the application field of ceramic bearing greater. The new materials, new processes and new technologies are capable to serve the production better.

Blue Northern Energy Acquires Quicksilver Biodiesel Technology

Blue Northern Energy is revitalizing the biodiesel industry. BNE’s mission is to create a sustainable and profitable biofuel production industry throughout the United States. BNE combines the latest technology advances, refining processes and innovative minds to develop sustainable and profitable biodiesel production facilities. BNE provides guidance and solutions to businesses and communities in their endeavors to develop new biodiesel production facilities or retrofitting existing facilities to make them sustainable and profitable. Through its work and expertise BNE, distinguishes itself as the leader in the renewable energy field.

Blue Northern Energy (BNE) has acquired a unique technology for producing biodiesel fuel. The Quicksilver Biodiesel Technology (QSB) is a continuous biodiesel production process by the trans-esterification of vegetable oils. Multiple feedstocks may be used, allowing the lowest cost feedstocks to be used. The ability to modify the process continuously, as the feedstocks change by modulating the other reactants to the process rather than changing batch recipes, makes it a highly flexible and more efficient process. The process also allows a reduction in capital cost of up to 40% and a reduction in operating cost through lower energy cost of up to 30%. These benefits of the technology have been confirmed through a 3rd party assessment completed by the Center for Process Innovation.

The QSB technology has been extensively tested at the pilot plant in Budapest, Hungary. Feedstocks from Europe as well as the USA have been demonstrated, both individually as well as blends.

Developing and improving the technology is a high priority for BNE, and fundamental to our global expansion plans. In order to support this, BNE will be establishing a new Innovation Center located next to the first biodiesel plant in Newton, Illinois. The center will have the capability to demonstrate future feedstock processing and perform extensive fuel quality measurements for BNE plants and experimental samples.

It is the administrator of the BN National Trail facility from conceptualization, development, construction to management. This facility exemplifies the revolutionary technology of BNE and production process that utilized multiple crops, edible and non-edible, for sustainable, high quality and profitable biodiesel production.

BNE’s staff will increase to support this technology program. A senior chemical process expert will be brought on board to perform mass and energy balance calculations and design the chemical process for advanced feedstocks. Also, a technical engineering manager will be brought on to manage the creation of the high level design documents for future plants

BNE’s goal through sharing new technology, management and finance procedures is that BNE will empower communities to establish new biofuel production facilities and for existing facilities to be retrofitted with new technology to become more profitable and efficient.
