Objectives: The aim of this study is to review how health technology assessments (HTA) of medical tests incorporate intermediate outcomes in conclusions about the effectiveness of tests on improving health outcomes.Methods: Systematic review of English-language test assessments in the HTA database from January 2005 to February 2010, supplemented by a search of the Web sites of International Network of Agencies for Health Technology Assessment (INAHTA) members.Results: A total of 149 HTAs from eight countries were assessed. Half evaluated tests for screening or diagnosis, a third for disease classification (including staging, prognosis, monitoring), and a fifth for multiple purposes. In seventy-one HTAs (48 percent) only diagnostic accuracy was reported, while in seventeen (11 percent) evidence of health outcomes was reported in addition to accuracy. Intermediate outcomes, mainly the impact of test results on patient management, were considered in sixty-one HTAs (41 percent). Of these, forty-seven identified randomized trials or observational studies reporting intermediate outcomes. The validity of these intermediate outcomes as a surrogate for health outcomes was not consistently discussed; nor was the quality appraisal of this evidence. Clear conclusions about whether the test was effective were included in approximately 60 percent of HTAs.Conclusions: Intermediate outcomes are frequently assessed in medical test HTAs, but interpretation of this evidence is inconsistently reported. We recommend that reviewers explain the rationale for using intermediate outcomes, identify the assumptions required to link intermediate outcomes and patient benefits and harms, and assess the quality of included studies.

150 Background: Anti-angiogenesis (AA) drugs (e.g., bevacizumab) are expensive and their clinical benefit in metastatic breast cancer (MBC) has been challenged. Healthcare reform and financial pressures prioritize programs which improve patient quality of care and reduce costs of unnecessary care. Angiogenesis-specific imaging tests (A-IT) under development have potential to offer earlier, accurate determination of response. For A-IT-identified responders, AA treatment would be continued. For patients identified as non-responders, futile AA treatment and associated toxicities can be avoided and alternative therapies initiated. Methods: A decision-tree model was developed to estimate the impact of A-IT from determination of AA therapy eligibility through to disease progression. Key decision nodes were presence/absence of A-IT (assessing change in biomarker expression across 2 PET/CT scans: at AA eligibility, then after one cycle of AA), A-IT sensitivity/specificity (SE/SP) and clinician adherence to test results (tied to belief that results are valid enough to stop AA therapy). Key model inputs (and base case values): 1) median time to progression (TTP) for current MBC patients on AA therapies (9.5 months); 2) median TTP for A-IT identified responders (13 months); 3) costs of bevacizumab, one cycle ($5,200); 4) percentage of AA patients with hemorrhage (4%); 5) costs of hemorrhaging, per event ($14,694); 6) per patient costs for A-IT ($6,000); 7) estimated SE/SP of A-IT – 95%/75%; and 8) clinician adherence to test results (75%). Results: Based on a cohort of 100 MBC patients, use of A-IT results in 29 patients avoiding futile AA therapy with a saving of $460,000, versus a scenario where A-IT was not used. One-way threshold sensitivity analysis shows A-IT is cost-saving if SP >62% or when clinician adherence is ≥63%; results are not sensitive to AA hemorrhage rate. Conclusions: Use of A-IT could improve quality of care by optimizing AA therapy, i.e., by identifying responders who will experience survival benefit and non-responders who can avoid futile therapy and toxicity risks. Significant cost savings may be possible as a result of early determination of response to AA drugs.

305 Background: For many patients going through the cancer diagnosis journey, the time from suspicion to diagnosis or rule-out can be a confusing and anxious time. To better support patients during this time, Cancer Care Ontario (CCO) is supporting Diagnostic Assessment Programs (DAPs) and the web-based tool known as the Diagnostic Assessment Program–Electronic Pathway Solution (DAP-EPS). DAPs consist of multi-disciplinary healthcare teams who provide diagnostic and supportive care services in a patient-focused environment, improving access to care and the patient experience. DAPs help manage and coordinate a patient’s diagnostic care from testing to a definitive diagnosis and part of this support involves providing access to personal health information through the DAP-EPS. This work was undertaken to determine the best approach to sharing test results with patients, including the type of test results that should be released and the most effective method for sharing these results with patients, from both the patient and provider perspective. Methods: The exploratory project involved conducting key informant interviews with individuals who had been involved with implementing similar patient portals, a targeted literature review, and a series of engagement sessions with physicians to measure the clinical response to this new strategy. Results: Initial discussions with patients and nurses yielded a strong endorsement for releasing all results, with no time delay. Key Informant interviews yielded similar results from the majority of the hospital contacts consulted. The environmental scan did not suggest that releasing results was associated with any adverse patient or provider effects. The physician engagement sessions generated both positive and negative feedback but overall, doctors were comfortable releasing all results, provided there was a delay built into the system. Conclusions: The release of diagnostic test results is seen as a valuable component of quality of care from the perspective of informing and empowering the patient. As the DAP-EPS moves forward with this initiative, the DAP program will continue to monitor the impact that the release of results has on both patients and providers.

Fusarium infection is a worldwide agricultural problem of billion dollar proportions globally, and it has increasingly threatened entire regional food supplies. In addition to the toxin deoxynivalenol (DON), Fusarium species express digestive enzymes that degrade starch and protein, affecting the quality of infected grains, especially wheat processing performance which depends largely on gluten proteins. In this study, the impact of Fusarium protease on the functionality of Canada Western Red Spring (CWRS) wheat was assessed by adding Fusarium-damaged kernels (FDK) to a FDK-free base wheat sample. Digestion of beta-casein by extracts of flours, milled from sound and FDK-spiked wheat samples, demonstrated elevated cleavage in FDK-spiked flour extracts as follows: N-terminal to lysine (eight-fold), N- and C-terminal to isoleucine (four-fold and three-fold, respectively), N-terminal to tyrosine (three-fold) and C-terminal to arginine at P1′ (five-fold). Comparison of abbreviated (45 min) and standard (135 min) extensigraph test results indicated that desirable increases in dough resistance to extension (Rmax) due to gluten re-polymerization after longer resting were partially to completely counteracted in FDK-spiked flours in a dose-dependent manner. Baking tests confirmed that while loaf volume is similar, proofed dough from FDK-spiked samples caused detectable loaf collapse at 3% FDK. Extensigraph Rmax and Fusarium protease levels were inversely related, and effected by both the extent and severity of infection. While the current FDK tolerances for grading Canadian wheat can effectively control protease damage, prevalence of deoxynivalenol (DON) weak- and non-producing Fusarium strains/species (e.g., F. avenaceum) in some growing regions must be considered to protect functionality if grading is solely based on DON content.

The Impact

The structure and mechanical properties of eight steel gas pipeline single-seam and double-seam pipes that were in operation were studied. It is shown that the degree of corrosion damage to pipe surfaces depends on the chemical composition of the steels. In the studied steels, a significant variation in the hydrogen content between neighboring volumes and the studied pipes was revealed. According to electron-fractographic analysis , there is no significant difference in the degree of embrittlement of the base metal, the weld and the zone of thermal influence. A noticeable effect of hydrogen absorption of steels on the coefficient of anisotropy of the impact toughness has been established, which causes a decrease in the impact toughness on transverse samples to a greater extent than on longitudinal ones. According to the results of mechanical tests for tensile and impact bending, it was found that the restored welded pipes are suitable for use in structures from the first to the fourth groups for the construction, repair and reconstruction of industrial and civil facilities. Naturally, this implies the need for their restoration repair.

This article refers to the traditional solution of the non-dismantable sampler and to the dismantable sampler applied as a new solution. This research describes the results of a research project on how the structure of the sampler for assembling and storage of LPG samples influences the representativeness of samples under study. The research was carried out in two directions : analysis of gas samples for the current PN-EN 589, PN-EN ISO 4257 standards and analysis of microscopic and macroscopic inner surface of the sampler. It was observed the formation of contamination layers in samplers. The chemical composition of the layers was examined and identified possible impact on changing the quality parameters of LPG. Based on the conducted research and analysis, the impact of the changed structure on the quality parameters of the LPG fuel and its representativeness in reference to the part of the cargo from which it had been taken can be assessed. Allow to conclude the thesis that the structure of the dismantable sampler followed internal cylinder surface treatment affects the representativeness of the samples collected and analyzed type of LPG gas. The construction of the sampler and possible of cleaning sampler is particularly important for qualitative parameters such gases as corrosive to copper and sulfur content of the total. Impurities that may be present in LPG, derived from refinery and petrochemical processes (ammonia, water, sulfur, methanol, higher hydrocarbons, dirt) and the distribution system are causing the occurrence of secondary reactions. Results occurring secondary reactions adversely affect the quality of the LPG. The researched solution on the dismantled sampler was patented, implemented, and applied in practice. The possibility to dismantle and thoroughly clean the sampler prior to sample collection enhances the certainty of obtaining highly representative samples and credible test results.

In paper the impact of intentionally chlorine-contaminated fuel on nitrogen oxides emission control elements in compression engine was described. The quality of fuel used is of key importance for the failure-free operation of the engine. Fuel contamination can occur mainly at the transport or storage stage.The main attention was paid to the EGR heat exchanger, which is used for exhaust gases recirculation, being one of the ways to reduce the emission of harmful NOx. The tests were conducted under laboratory conditions (research engine stand tests) in cycles consisting of four phases. The fuel used was intentionally contaminated with chlorine. The test was interrupted after 250 hours at the engine failure and deposits appearance at the EGR heat exchanger. Test results of chemical composition of deposits, analytical methods used and sources and the cause of deposits appearance were described in present paper.

Introduction: Immunotherapy has proven its efficacy in multiple randomized control trials (RCT) in treating allergic rhinitis (AR) as it induces induces long term remission after discontinuation and prevent new sensitization. Objective: Our aim is to look into earliest improvement of quality of life (QOL) in AR patient treated with Sublingual immunotherapy (SLIT). Methodology: Patients who were sensitized to dust mites (Dermatophagoides farinae, Dermatophagoides pteronyssinus and Blomia tropicalis) were enrolled into the study. All patients were treated with SLIT for 6 months. The patients were assessed using rhinoconjunctivitis quality of life questionnaires (RQLQ) and peak nasal inspiratory flow (PNIF) pre-treatment at 1, 3 and 6 months post SLIT. The usage of intranasal corticosteroids (INS) and antihistamine were documented in medication diary. The data for pre and post treatment for RQLQ results were analysed using paired T-test and medication diary were analysed using ANOVA test. Results: A total of 53 patients were enrolled in the study. The mean RQLQ score showed significant result at 3 and 6 months post SLIT (p<0.05). Significant improvement seen in the mean PNIF value pre-treatment (81.54 L/min ±29.36 ) compared to mean PNIF value at 3 months (92.0L/min ±29.03 ) and 6 months (96.13L/min ±26.67) post SLIT (p<0.05). The dependency of patients towards pharmacotherapy also showed a significant reduction at 3 and 6 months post SLIT (p<0.05). Conclusion: Our study showed a significant improvement of patients’ quality of life as early as 3 months of post SLIT treatment.
