Background:
The SOURCE 3 Registry (SAPIEN Aortic Bioprosthesis European Outcome) is a European multicenter, observational registry of the latest generation of transcatheter heart valve, the SAPIEN 3 (Edwards Lifesciences, Irvine, CA). Its purpose is to document outcomes of clinical safety and performance after European approval was given.

Methods:
Here, we present the 30-day outcome of the SOURCE 3 Registry. All data are self-reported, and all participating centers have committed to support their consecutive experience with the SAPIEN 3 transcatheter heart valve, dependent on patient consent, before the start of the study. Adverse events are defined with Valve Academic Research Consortium 2 criteria and adjudicated by an independent clinical events committee.

Results:
A total of 1950 patients from 80 centers in 10 countries were enrolled between July 2014 and October 2015. Of those, 1947 patients underwent transcatheter aortic valve implantation (TAVI) with the SAPIEN 3 (mean age, 81.6±6.6 years; 48.1% female). Main comorbidities included coronary artery disease (51.5%), renal insufficiency (27.4%), diabetes mellitus (29.5%), chronic obstructive pulmonary disease (16.0%), and a mean logistic EuroSCORE of 18.3±13.2. Transfemoral access was used in 87.1% (n=1695); nontransfemoral, in 252 patients. Conscious sedation was used in 59.9% of transfemoral procedures, and in 50% of patients, TAVI was performed without aortic balloon valvuloplasty. Implantation success (1 valve in the intended location) was 98.3%. Conversion to conventional surgery (0.6%) and use of cardiopulmonary bypass (0.7%) were rare. Adverse events were low, with site-reported 30-day all-cause mortality of 2.2%, cardiovascular mortality of 1.1%, stroke of 1.4%, major vascular complications of 4.1%, life-threatening bleeding of 5%, and post-TAVI pacemaker implantation of 12%. Moderate or greater paravalvular regurgitation was observed in 3.1% of reporting patients.

Conclusions:
Results from the SOURCE 3 Registry demonstrate contemporary European trends and good outcomes of TAVI in daily practice when this third-generation TAVI device is used.
State Public Health Laboratory System Quality Improvement Activities
Authors: Su Bertina , Vagnone Paula Snippes 
Published: January 2017

The Association of Public Health Laboratories (APHL) and the APHL Laboratory Systems and Standards Committee manage the Laboratory System Improvement Program (L-SIP). One component of L-SIP is an assessment that allows the members and stakeholders of a laboratory system to have an open and honest discussion about the laboratory system's strengths and weaknesses. From these facilitated discussions, gaps and opportunities for improvement are identified. In some cases, ideas for how to best address these gaps emerge, and workgroups are formed. Depending on resources, both monetary and personnel, laboratory staff will then prioritize the next component of L-SIP: which quality improvement activities to undertake. This article describes a sample of quality improvement activities initiated by several public health laboratories after they conducted L-SIP assessments. These projects can result in more robust linkages between system entities, which can translate into improvements in the way the system addresses the needs of stakeholders.

Authors: Armour Patricia A. , Nguyen Linh M. , Lutman Michelle L. , Middaugh John P. 
Published: January 2017

Objectives. Infections caused by respiratory viruses are associated with recurrent epidemics and widespread morbidity and mortality. Routine surveillance of these pathogens is necessary to determine virus activity, monitor for changes in circulating strains, and plan for public health preparedness. The Southern Nevada Health District in Las Vegas, Nevada, recruited five pediatric medical practices to serve as sentinel sites for the Pediatric Early Warning Sentinel Surveillance (PEWSS) program. Methods. Sentinel staff collected specimens throughout the year from ill children who met the influenza-like illness case definition and submitted specimens to the Southern Nevada Public Health Laboratory for molecular testing for influenza and six non-influenza viruses. Results. Laboratory results were analyzed and reported to the medical and general communities in weekly bulletins year-round. PEWSS data were also used to establish viral respiratory seasonal baselines and in influenza vaccination campaigns. The surveillance program was evaluated using the Centers for Disease Control and Prevention's (CDC's) Updated Guidelines for Evaluating Public Health Surveillance Systems. PEWSS met three of six program usefulness criteria and seven of nine surveillance system attributes, which exceeded the CDC Guidelines evaluation criteria for a useful and complete public health surveillance program. Conclusion. We found that PEWSS is a useful and complete public health surveillance system that is simple, flexible, accessible, and stable.

Published: January 2017

Objective. Pre-immigration tuberculosis (TB) screening, followed by post-arrival rescreening during the first year, is critical to reducing TB among foreign-born people in the United States. However, existing U.S. public health surveillance is inadequate to monitor TB among immigrants during subsequent years. We developed and tested a novel method for ascertaining post-U.S.-arrival TB outcomes among high-TB-risk immigrant cohorts to improve surveillance. Methods. We used a probabilistic record linkage program to link pre-immigration screening records from U.S.-bound immigrants from the Philippines ( n=422,593) and Vietnam ( n=214,401) with the California TB registry during 2000–2010. We estimated sensitivity using Monte Carlo simulations to account for uncertainty in key inputs. Specificity was evaluated by using a time-stratified approach, which defined false-positives as TB records linked to pre-immigration screening records dated after the person had arrived in the United States. Results. TB was reported in 4,382 and 2,830 people born in the Philippines and Vietnam, respectively, in California during the study period. Of these TB cases, records for 973 and 452 cases of people born in the Philippines and Vietnam, respectively, were linked to pre-immigration screening records. Sensitivity and specificity of linkage were 89% (90% credible interval [CrI] 83, 97) and 100%, respectively, for the Philippines, and 90% (90% CrI 83, 98) and 99.9%, respectively, for Vietnam. Conclusion. Electronic linkage of pre-immigration screening records to a domestic TB registry was feasible, sensitive, and highly specific in two high-priority immigrant cohorts. Transnational record linkage can be used for program evaluation and routine monitoring of post-U.S.-arrival TB risk among immigrants, but requires interagency data sharing and collaboration.

Objective. This study aimed to characterize premature mortality among people diagnosed with HIV infection from 2000 to 2009 in Florida, by sex and race/ethnicity, to estimate differences in premature mortality that could be prevented by linkage to HIV care and treatment. Methods. Florida surveillance data for HIV diagnoses (excluding concurrent AIDS diagnoses) were linked with vital records data to ascertain deaths through 2011. Years of potential life lost (YPLL) were obtained from the expected number of remaining years of life at a given age from the U.S. sex-specific period life tables. Results. Among 41,565 people diagnosed with HIV infection during the study period, 5,249 died, and 2,563 (48.8%) deaths were due to HIV/AIDS. Age-standardized YPLL (aYPLL) due to HIV/AIDS per 1,000 person-years was significantly higher for females than males (372.6, 95% confidence interval [CI] 349.8, 396.2 vs. 295.2, 95% CI 278.4, 312.5); for non-Hispanic black (NHB) females than non-Hispanic white (NHW) and Hispanic females (388.2, 95% CI 360.7, 416.9; 294.3, 95% CI 239.8, 354.9; and 295.0, 95% CI 242.9, 352.5, respectively); and for NHB males compared with NHW and Hispanic males (378.7, 95% CI 353.7, 404.7; 210.6, 95% CI 174.3, 250.8; and 240.9, 95% CI 204.8, 280.2, respectively). In multilevel modeling controlling for individual factors, NHB race was associated with YPLL due to HIV/AIDS for women ( p=0.04) and men ( p<0.001). Conclusion. Among people diagnosed with HIV infection, females and NHB people had a disproportionately high premature mortality from HIV/AIDS, suggesting the need for enhanced efforts to improve linkage to and retention in care and medication adherence for these groups.

Objective. Liver disease is a potential complication from using dietary supplements. This study investigated an outbreak of non-viral liver disease associated with the use of OxyELITE Pro™, a dietary supplement used for weight loss and/or muscle building. Methods. Illness details were ascertained from MedWatch reports submitted to the U.S. Food and Drug Administration (FDA) describing consumers who ingested OxyELITE Pro alone or in combination with other dietary supplements. FDA's Forensic Chemistry Center analyzed samples of OxyELITE Pro. Results. From February 2012 to February 2014, FDA received 114 reports of adverse events of all kinds involving consumers who ingested OxyELITE Pro. The onset of illness for the first report was December 2010 and for the last report was January 2014. Thirty-three states, two foreign nations, and Puerto Rico submitted reports. Fifty-five of the reports (48%) described liver disease in the absence of viral infection, gallbladder disease, autoimmune disease, or other known causes of liver damage. A total of 33 (60%) of these patients were hospitalized, and three underwent liver transplantation. In early 2013, OxyELITE Pro products entered the market with a formulation distinct from products sold previously. The new formulation replaced 1,3-dimethylamylamine with aegeline. However, the manufacturer failed to submit to FDA a required “new dietary ingredient” notice for the use of aegeline in OxyELITE Pro products. Laboratory analysis identified no drugs, poisons, pharmaceuticals, toxic metals, usnic acid, N-Nitroso-fenfluramine, pyrrolizidine alkaloids, aristocholic acid, or phenethylamines in the products. Conclusions. Vigilant surveillance is required for adverse events linked to the use of dietary supplements.
Water-Contact-Angle Studies of Fabrics Radiation-Grafted with Methylhydrogensiloxane
Authors: Nishide Shinko , Shimizu Harumichi 
Published: January 2017

The water-contact angles of the polymethylhydrogensiloxane (silicone)-grafted fabrics (wool, cotton, Vinylon, rayon, acetate, Tetoron, nylon, and silk) prepared by irradiation were measured and the results support the following conclusions: 1. For the same degree of grafting, the relation between the water-contact angles and the roughness factors (defined as the number of yarn crossover points per-unit-area) of various fabrics is linear. It is concluded that the surfaces of grafted fabrics are in the same state regardless of kinds of fabrics. 2. On fabrics of the same roughness the water-contact angles of grafted samples are greater by about 10° than those of the silicone-coated samples, which are padded with silicone, not irradiated, and heated. This fact can be explained by the hypothesis that the upheavals on the surface of a fabric are increased by radiation grafting. 3. By repeated washing with petroleum solvent, the water-contact angles of grafted fabrics decrease a few degrees after one washing and then do not change further even after repeated washing. This result suggests that the grafted silicone is “set” into a conformation which is not appreciably altered in spite of repeated solvent washing.
A Multilayer Theory for Gas Sorption
Authors: Dent R. W. 
Published: January 2017

A multilayer model is proposed which predicts the equilibrium sorption isotherms for pure gases in Part I and for binary gas mixtures in Part II. This first part deals with the sorption of a pure gas or vapor, particularly by polymers. The model and equations are significantly different from those presently most used. The model gives good fits to the data against which it has been tested, particularly when used with sigmoidal isotherms. It allows the thermodynamic parameters to be calculated and gives important knowledge about the distribution and location of sorbed species.
Assessment of Reserves in the WX-4 Wilcox Deltaic Sandstones in the Rio Grande Embayment
Authors: Lerche I. 
Published: January 2017

An estimate is given of expected total gas reserves in place in the WX-4 Deltaic Sandstones of the Wilcox Formation in the Rio Grande Embayment based upon open-domain information taking into account detailed production figures from Wilcox reservoirs along the shelf trend. The overall estimate would suggest that a total amount of gas in place is roughly between 5 to 23 TCF (at STP) with a likely value of 14 TCF. Since production statistics indicate 6 TCF already produced with an average depletion of 83%, for a total expected ultimate recoverable in known reservoirs of around 7.2 TCF, the implication is that a maximum of between 0 to 15 TCF remain to be discovered, with a most likely discoverable amount of 6-7 TCF.
Stationarity and Cointegration Tests of the Ohlson Model
Authors: Qi Daqing D. , Wu Y. Woody , Xiang Bing 
Published: January 2017

This paper investigates the time-series properties of the Ohlson (1995) model and examines their implications for empirical studies that use time-series data but do not explicitly account for such properties. Based on a sample of 95 firms with complete data from 1958 to 1994, we show that the null hypothesis that market value and book value are nonstationary cannot be rejected for most of the sample firms. More importantly, book value and residual income do not cointegrate with market value for 80 percent of the sample firms. We demonstrate the importance and relevance of the time-series properties of the model to OLS regressions by showing that the OLS out-of-sample forecasts of market value are significantly more accurate and less biased for the cointegrated firms than for the non-cointegrated firms. We also explore methods to improve the specification of OLS regressions based on the Ohlson (1995) model and suggest that scaling the variables with lagged market value can significantly alleviate the problem with nonstationarity of the unsealed time-series data. While the generality of our results is limited by the survivorship bias of our sample, we believe that our paper has some important implications for studies motivated by the Ohlson (1995) model. First, because market value and book value are nonstationary and book value and residual income do not cointegrate with market value for most firms, the other information variable has to be nonstationary so that a linear combination of the independent variables can cointegrate with market value. Second, direct tests of the Ohlson (1995) model through OLS regressions using time-series data are questionable because they are likely to be misspecified. This may partially explain the underestimation of market value widely documented by previous studies and the significant difference between parameters predicted by the Ohlson (1995) model and estimated from OLS regressions. Third, our results also suggest that scaling the data with lagged market value can mitigate the problems with nonstationarity. For studies using unsealed time-series data, a cointegration test should be conducted first and a sensitivity analysis based on the cointegrated sub-sample should be performed to examine whether the results based on the full sample are robust.
The Predictive Value of Analyst Characteristics
Authors: Brown Lawrence D. , Mohd Emad 
Published: January 2017

While numerous intuitively appealing characteristics of individual analyst earnings forecast accuracy have been identified, the extant literature has provided no evidence regarding the out-of-sample predictive validity of these characteristics. We examine whether these characteristics possess incremental predictive ability vis-à-vis forecast age, the control variable of these studies. We compare the predictive ability of a consensus forecast based solely on forecast age (Age) with that of a six-factor model consisting of forecast age plus five analyst characteristics suggested by the literature (Model). We use the dual evaluative criteria suggested by Foster (1977) and employed numerous times thereafter to assess predictive ability: (1) the ability to predict the next number in the time series and (2) the ability to approximate the capital market's earnings expectation. We show that Age predicts as well as Model using both predictive ability criteria. Because Model consists of Age plus five other factors, it is cost-beneficial to use Age in lieu of Model for predictive purposes. FASB Statement of Financial Accounting Concepts No. 2 (1980) identifies predictive value as a criterion of information relevance. We show that analyst characteristics have no relevance for the purpose of obtaining better predictions of the next quarterly earnings number vis-à-vis a simpler model based on forecast age. There are many reasons for identifying individual analyst-based characteristics, but predictive ability of the next quarterly number is not one of them.
Local Validation of Mandate Consultant: An Expert System for Assuring Compliance in the IEP Process

Published: January 2017

When schools fail to comply with state and federal regulations regarding IEP development, students, faculty and programs are at risk. Many schools currently conduct internal file reviews to identify and correct compliance problems. Unfortunately, special education file review is a time consuming task which is usually done by an experienced special educator or school psychologist. Expert system computer programs are designed to allow personnel with relatively low skill levels to complete a task which usually requires a good deal of training and experience. Mandate Consultant is an expert system designed to assist in special education file review. This study uses an easily replicable model to compare the file review performance of a secretary using Mandate Consultant with that of a special education expert. The secretary produced reports which were five times more accurate and over twenty times less expensive than the reports generated by the expert. Expert systems may provide a practical tool for reducing costs associated with assuring legal compliance.
Time Varying Volatility in the Indian Stock Market
Authors: Kaur Harvinder 
Published: January 2017

This paper investigates the nature and characteristics of stock market volatility in India. The volatility in the Indian stock market exhibits characteristics similar to those found earlier in many of the major developed and emerging stock markets. Various volatility estimators and diagnostic tests indicate volatility clustering, i.e., shocks to the volatility process persist and the response to news arrival is asymmetrical, meaning that the impact of good and bad news is not the same. Suitable volatility forecast models are used for Sensex and Nifty returns to show that: The ‘day-of-the-week effect’ or the ‘weekend effect’ and the ‘January effect’ are not present while the return and volatility do show intra-week and intra-year seasonality. The return and volatility on various weekdays have somewhat changed after the introduction of rolling settlements in December 1999. There is mixed evidence of return and volatility spillover between the US and Indian markets. The empirical findings would be useful to investors, stock exchange administrators and policy makers as these provide evidence of time varying nature of stock market volatility in India. Specifically, they need to consider the following findings of the study: For both the indices, among the months, February exhibits highest volatility and corresponding highest return. The month of March also exhibits significantly higher volatility but the magnitude is lesser as compared to February. This implies that, during these two months, the conditional volatility tends to increase. This phenomenon could be attributed to probably the most significant economic event of the year, viz., presentation of the Union Budget. The investors, therefore, should keep away from the market during March after having booked profits in February itself. The surveillance regime at the stock exchanges around the Budget should be stricter to keep excessive volatility under check. Similarly, the month of December gives high positive returns without high volatility and, therefore, offers good opportunity to the investors to make safe returns on Sensex and Nifty. On the contrary, in the month of September, i.e., the time when the third quarter corporate results are announced, volatility is higher but corresponding returns are lower. The situation is, therefore, not conducive to investors. The ‘weekend effect’ or the ‘Monday effect’ is not present. For other weekdays, the ‘higher (lower) the risk, higher (lower) the return’ dictum does not hold consistently and Wednesday provides higher returns with lower volatility making it a good day to invest. The domestic investors and the stock exchange administrators do not need to lose sleep over gyrations in the major US markets since there is no conclusive evidence of consistent relationship between the US and the domestic markets. The volatility forecast models presented for Sensex and Nifty can be used to forecast future volatility of these indices.
