Abstract

The article presents a study which determined the inter-rater reliability between the Veterans Affairs (VA) Dementia ICD Code List and the Chronic Conditions Warehouse (CCW) Alzheimer's disease and related disorders (ADRD) algorithm when applied to a cohort of veterans hospitalized with heart failure. Topics include sample characteristics, comparison of ICD-10 codes in the VA and CCW ADRD algorithms, and limitations of the study.

Abstract

Background: Medications are one of the most easily modifiable risk factors for motor vehicle crashes (MVCs) among older adults, yet limited information exists on how the use of potentially driver‐impairing (PDI) medications changes following an MVC. Therefore, we examined the number and types of PDI medication classes dispensed before and after an MVC. Methods: This observational study included Medicare fee‐for‐service beneficiaries aged ≥67 years who were involved in a police‐reported MVC in New Jersey as a driver between 2008 and 2017. Analyses were conducted at the "person‐crash" level because participants could be involved in more than one MVC. We examined the use of 36 PDI medication classes in the 120 days before and 120 days after MVC. We described the number and prevalence of PDI medication classes in the pre‐MVC and post‐MVC periods as well as the most common PDI medication classes started and stopped following the MVC. Results: Among 124,954 person‐crashes, the mean (SD) age was 76.0 (6.5) years, 51.3% were female, and 83.9% were non‐Hispanic White. The median (Q1, Q3) number of PDI medication classes was 2 (1, 4) in both the pre‐MVC and post‐MVC periods. Overall, 20.3% had a net increase, 15.9% had a net decrease, and 63.8% had no net change in the number of PDI medication classes after MVC. Opioids, antihistamines, and thiazide diuretics were the top PDI medication classes stopped following MVC, at incidences of 6.2%, 2.1%, and 1.7%, respectively. The top medication classes started were opioids (8.3%), skeletal muscle relaxants (2.2%), and benzodiazepines (2.1%). Conclusions: A majority of crash‐involved older adults were exposed to multiple PDI medications before and after MVC. A greater proportion of person‐crashes were associated with an increased rather than decreased number of PDI medications. The reasons why clinicians refrain from stopping PDI medications following an MVC remain to be elucidated. [ABSTRACT FROM AUTHOR]

74. Domain and Language Independent Feature Extraction for Statistical Text Categorization

Author

Bayer, Thomas, Renz, Ingrid, Stein, Michael, and Kressel, Ulrich

Subjects
Computer Science - Computation and Language
Abstract

A generic system for text categorization is presented which uses a representative text corpus to adapt the processing steps: feature extraction, dimension reduction, and classification. Feature extraction automatically learns features from the corpus by reducing actual word forms using statistical information of the corpus and general linguistic knowledge. The dimension of feature vector is then reduced by linear transformation keeping the essential information. The classification principle is a minimum least square approach based on polynomials. The described system can be readily adapted to new domains or new languages. In application, the system is reliable, fast, and processes completely automatically. It is shown that the text categorizer works successfully both on text generated by document image analysis - DIA and on ground truth data., Comment: 12 pages, TeX file, 9 Postscript figures, uses epsf.sty

82. Evidence of Circular Business Model Innovation in Agribusinesses in Rwanda.

Abstract

African economies are susceptible to global food market shocks and prices. Incorporating circular and regenerative strategies into domestic agricultural production and processing has been identified as a possible solution. This requires transforming linear business models into circular models. However, lessons from circular innovations are limited to examples from advanced economies focusing mainly on industrial technology. Little is known about circularity in agribusinesses in emerging economies. This research addresses this gap by assessing various circular business model innovations found in agribusinesses in Rwanda. The Rwandan government is committed to the circular economy model, and agriculture is a priority and targeted sector for the CE transition. Qualitative and quantitative data from 16 companies were collected. Initial findings indicate that examples of circular practices primarily focus on reusing, repairing, repurposing material, and regenerating soil fertility. Particular challenges are related to a lack of infrastructure, such as locally available packaging materials and machinery. [ABSTRACT FROM AUTHOR]
