Challenges in Estimating the Impact of Vaccination with Sparse Data.

Epidemiology 2019 Jan;30(1):61-68

From the Department of Epidemiology of Microbial Diseases, Yale School of Public Health, New Haven, CT.

Background: The synthetic control model is a powerful tool to quantify the population-level impact of vaccines because it can adjust for trends unrelated to vaccination using a composite of control diseases. Because vaccine impact studies are often conducted using smaller, subnational datasets, we evaluated the performance of synthetic control models with sparse time series data. To obtain more robust estimates of vaccine impacts from noisy time series, we proposed a possible alternative approach, STL+PCA method (seasonal-trend decomposition plus principal component analysis), which first extracts smoothed trends from the control time series and uses them to adjust the outcome.

Rapid Determination of Procyanidins Using MALDI-ToF/ToF Mass Spectrometry.

J Agric Food Chem 2018 Oct 16;66(43):11355-11361. Epub 2018 Oct 16.

University of Illinois College of Pharmacy, 833 South Wood Street , Chicago , Illinois 60612 , United States.

Although procyanidins constitute a unique class of polymeric plant secondary metabolites with a variety of biological properties including potent antioxidant activity, structure determination has been challenging, and structures of many complex procyanidins remain uncertain. To expedite the characterization of procyanidins, negative ion matrix-assisted laser desorption ionization high-energy collision-induced dissociation tandem time-of-flight (MALDI-ToF/ToF) mass spectra of 20 isolated procyanidins containing catechin and epicatechin subunits with degrees of polymerization up to five were obtained and evaluated. Structurally significant fragmentation pathways of singly charged, deprotonated molecules were identified representing quinone methide, heterocyclic ring fission, and retro-Diels-Alder fragmentation.

The "RCT augmentation": a novel simulation method to add patient heterogeneity into phase III trials.

BMC Med Res Methodol 2018 Jul 6;18(1):75. Epub 2018 Jul 6.

LASER Core, Paris, France.

Background: Phase III randomized controlled trials (RCT) typically exclude certain patient subgroups, thereby potentially jeopardizing estimation of a drug's effects when prescribed to wider populations and under routine care ("effectiveness"). Conversely, enrolling heterogeneous populations in RCTs can increase endpoint variability and compromise detection of a drug's effect. We developed the "RCT augmentation" method to quantitatively support RCT design in the identification of exclusion criteria to relax to address both of these considerations. Read More

Using Clinical Research Networks to Assess Severity of an Emerging Influenza Pandemic.

Clin Infect Dis 2018 Jul;67(3):341-349

Rigshospitalet and Faculty of Health Sciences, University of Copenhagen, Denmark.

Background: Early clinical severity assessments during the 2009 influenza A H1N1 pandemic (pH1N1) overestimated clinical severity due to selection bias and other factors. We retrospectively investigated how to use data from the International Network for Strategic Initiatives in Global HIV Trials, a global clinical influenza research network, to make more accurate case fatality ratio (CFR) estimates early in a future pandemic, an essential part of pandemic response.

Methods: We estimated the CFR of medically attended influenza (CFRMA) as the product of probability of hospitalization given confirmed outpatient influenza and the probability of death given hospitalization with confirmed influenza for the pandemic (2009-2011) and post-pandemic (2012-2015) periods.

Luke Stark

Soc Stud Sci 2018 Apr;48(2):204-231

Department of Sociology, Dartmouth College, Hanover, NH, USA.

Recent public controversies, ranging from the 2014 Facebook 'emotional contagion' study to psychographic data profiling by Cambridge Analytica in the 2016 American presidential election, Brexit referendum and elsewhere, signal watershed moments in which the intersecting trajectories of psychology and computer science have become matters of public concern. The entangled history of these two fields grounds the application of applied psychological techniques to digital technologies, and an investment in applying calculability to human subjectivity. Today, a quantifiable psychological subject position has been translated, via 'big data' sets and algorithmic analysis, into a model subject amenable to classification through digital media platforms.

Laboratory of Materials Science, Tampere University of Technology, P.O. Box 589, FI-33101 Tampere, Finland.

In this study, we demonstrate a rapid treatment method for producing a needle-like nanowire structure on a hot-dip galvanized sheet at a temperature of 50 °C. The processing method involved only supercritical carbon dioxide and water to induce a reaction on the zinc surface, which resulted in growth of zinc hydroxycarbonate nanowires into flower-like shapes. This artificial patina nanostructure predicts high surface area and offers interesting opportunities for its use in industrial high-end applications. Read More

Appraising the holistic value of Lenvatinib for radio-iodine refractory differentiated thyroid cancer: A multi-country study applying pragmatic MCDA.

BMC Cancer 2017 04 17;17(1):272. Epub 2017 Apr 17.

LASER Analytica, Montreal, Quebec, Canada.

Background: The objective of the study was to reveal through pragmatic MCDA (EVIDEM) the contribution of a broad range of criteria to the value of the orphan drug lenvatinib for radioiodine refractory differentiated thyroid cancer (RR-DTC) in country-specific contexts.

Methods: The study was designed to enable comprehensive appraisal (12 quantitative, 7 qualitative criteria) in the current disease context (watchful waiting, sorafenib) of France, Italy and Spain. Data on the value of lenvatinib was collected from diverse stakeholders during country-specific panels and included: criteria weights (individual and social values); performance scores (judgments on evidence-collected through MCDA systematic review); qualitative impacts of contextual criteria; and verbal and written insights structured by criteria.

Effect of Diabetes Treatment-Related Attributes on Costs to Type 2 Diabetes Patients in a Real-World Population.

J Manag Care Spec Pharm 2017 Apr;23(4):446-452

4 Sanofi, Chilly-Mazarin Cedex, France.

Background: Type 2 diabetes mellitus (T2DM) results in a substantial economic burden on patients, health care systems, and society. Most literature assessing the cost of T2DM focuses on the long-term complications of the disease, the association between glucose control and cost, and patient characteristics resulting in poor and costly outcomes. However, it is likely that attributes specific to diabetes therapy can affect the use of costly resources. Read More
