Population-based reference values for the 1-min sit-to-stand test

OBJECTIVES: To determine reference values for the 1-min sit-to-stand (STS) test in an adult population. METHODS: Cross-sectional study nested within a nationwide health promotion campaign in Switzerland. Adults performed the STS test and completed questions on demographics and health behavior. RESULTS: 6,926 out of 7,753 (89.3 %) adults were able to complete the STS test. The median number of repetitions ranged from 50/min (25-75th percentile 41-57/min) in young men and 47/min (39-55/min) in young women aged 20-24 years to 30/min (25-37/min) in older men and 27/min (22-30/min) in older women aged 75-79 years. CONCLUSIONS: The reference values support the interpretation of 1-min STS test performance and identification of subjects with decreased lower body muscular strength and endurance

Tar Spot: An Understudied Disease Threatening Corn Production in the Americas

Tar spot of corn has been a major foliar disease in several Latin American countries since 1904. In 2015, tar spot was first documented in the United States and has led to yield losses of approximately 4.5 million t annually. Tar spot is caused by an obligate pathogen, Phyllachora maydis, and thus requires a living host to grow and reproduce. Due to its obligate nature, biological and epidemiological studies are limited and impact of disease in corn production has been understudied. Here we present the current literature and gaps in knowledge of tar spot of corn in the Americas, its etiology, distribution, impact and management strategies as a resource for understanding the pathosystem. This review is intended to guide current and future research and aid in the development of more effective management strategies for this disease.This is a manuscript of an article published as Valle-Torres, J., T.
