s did not perform well when applied to real-world EHR data, retraining the models using real-world EHR data and optimizing variable selection was beneficial for model performance. As clinical evidence evolves to include more real-world data, both industry and academia will likely search for ways to balance model optimization with generalizability. This study provides a pragmatic approach to applying RCT-trained models to real-world data.

While a number of studies have documented a notable decline in age-standardized prevalence in dementia in the U.S. population, relatively little is known about how dementia has declined for specific age and race groups, and the importance of changing educational attainment on the downward trend. We assess 1) how the trends in dementia prevalence may have differed across age and race groups and 2) the role of changing educational attainment in understanding these trends.

This paper estimates a series of logistic regression models using data from the Health and Retirement Study (2000-2014) to assess the relative annual decline in dementia prevalence and the importance of improving educational attainment for non-Hispanic Whites and non-Hispanic Blacks.

Consistent with other studies, we found significant declines in dementia for non-Hispanic Blacks and non-Hispanic Whites across this period. Nonetheless, these declines were not uniform across age and race groups. Non-Hispanic Blacks aged 65-74 had the steepest decline in this period. We also found that improved educational attainment in the population was fundamentally important in understanding declining dementia prevalence in the United States.

This study shows the importance of improvement in educational attainment in the early part of the 20 th century to understand the downward trend in dementia prevalence in the United States from 2000 to 2014.

Previous reports suggest high-specialized adolescent athletes may be at a higher risk of injury, worse sleep quality, and lower sport enjoyment than low-specialized athletes. Currently, sport specialization literature is primarily composed of adolescent athletes from a variety of sports. However, it is unknown if the findings on sport specialization from predominantly non-running athletes are generalizable to adolescent long-distance runners.

Compare injury history, running volume, quality of life, sleep habits, and running enjoyment among male and female middle- and high-school long-distance runners from different sport specialization levels.

Cross-sectional.

Online survey.

A total of 102 male (age=15.8±0.9 years) and 157 female (age=15.6±1.4 years) uninjured middle- and high-school athletes who participated in long-distance running activities (completion rate=50.7%).

Participants were stratified by sex and sport specialization level (low, moderate, high). Group differences in self-reported runni. However, high-specialized runners did not report a greater number of running-related injuries, lower quality of life, or lower sleep quality or duration as expected.

Contributions of African, Asian, Indian, Melanesian, Arabic and Persian populations have been suggested based on physical and cultural anthropology, oral tradition, linguistics and later also by archaeology. In the mid-20th century, increased knowledge of heredity rules and technical progress enabled the identification of African and Asian populations as main contributors. Recent access to the genomic landscape of Madagascar demonstrated pronounced regional variability in the relative contributions of these two ancestries, yet with significant presence of both African and Asian components throughout Madagascar. This article reviews the extent to which genetic results have settled historical questions concerning the origin of the Malagasy population. After an overview of the early literature, the genetic results of the 20th and 21th centuries are discussed and then complemented by the latest results in genome-wide analyses. click here While there is still much uncertainty regarding when, how and the circumstances under which the ancestors of the modern Malagasy population arrived on the island, we propose a scenario based on historical texts and genomic results.India represents an intricate tapestry of population substructure shaped by geography, language, culture, and social stratification. Although geography closely correlates with genetic structure in other parts of the world, the strict endogamy imposed by the Indian caste system and the large number of spoken languages add further levels of complexity to understand Indian population structure. To date, no study has attempted to model and evaluate how these factors have interacted to shape the patterns of genetic diversity within India. We merged all publicly available data from the Indian subcontinent into a data set of 891 individuals from 90 well-defined groups. Bringing together geography, genetics, and demographic factors, we developed Correlation Optimization of Genetics and Geodemographics to build a model that explains the observed population genetic substructure. We show that shared language along with social structure have been the most powerful forces in creating paths of gene flow in the subcontinent.
